three-measure keyboard passage from a Shostakovich concerto. Participants’instructions
were to practice until they were confident they could play the passage accurately at a
prescribed tempo in a retention test session the following day. We analyzed the practice
behaviors of each pianist in terms of numeric and nonnumeric descriptors and ranked the
pianists according to the overall performance quality of their retention tests. Results
indicated no significant relationship between the rankings of pianists’ retention test
performances and any of the following variables: practice time, number of total practice
trials, and number of complete practice trials. There were significant relationships
between retention test rankings and the percentage of all performance trials that were
performed correctly, r=–.51,thepercentageofcompleteperformancetrialsthatwere

the pianists practiced, a finding consistent with the results of related research.

Tens of thousands of hours in musicians’professional lives are devoted to individual
practice, the mechanism through which music skills are learned, refined, and main-
tained (Davidson, Howe, & Sloboda, 1997; Ericsson, 1997; Ericsson, Krampe, &
Tesch-Römer, 1993; Howe, Davidson, & Sloboda, 1998; Madsen, 2004). Although
this private aspect of musicianship is invisible to most nonmusicians, who typically
hear only public performances, musicians are well aware of the centrality of practice
in their life’s work.

Much of the extant research about music practice comprises comparisons among
practice interventions or imposed strategies, testing the relative efficacy of modeling
(Henley, 2001; Hewitt, 2001; Rosenthal, 1984; Rosenthal, Wilson, Evans, & Greenwalt,
1988), mental practice (Coffman, 1990; Lim & Lippman, 1991; Ross, 1985; Rubin-
Rabson, 1941a, 1941b, 1941c; Theiler & Lippman, 1995), practice reports (Wagner,
1975), and distraction indexes (Madsen & Geringer, 1981).
Only more recently have scholars begun to study in context and over time the
content of expert musicians’ practice (Chaffin & Imreh, 1997, 2001, 2002; Chaffin,
Imreh, Lemieux, & Chen, 2003; Gruson, 1988; Maynard, 2006; Williamon,
Valentine, & Valentine, 2002) and the practice of novices (McPherson, 2005;
Rohwer & Polk, 2006). Williamon and Valentine (2000), for example, observed
practice among pianists at four different skill levels and found that quality, not quan-
tity, of practice predicted performance quality at all levels of skill. In her study of
pianists’ practice, Gruson (1988) reported that the single best predictor of skill level
was the extent to which players repeated larger sections of music, rather than indi-
vidual notes. McPherson (2005), whose 3-year investigation of 157 beginning
instrumentalists is one of the most substantive to date, also noted that the strategies
employed in young musicians’ practice, not the amount of time devoted to practice,
were the best predictors of achievement.
Irrespective of the pedagogical implications of the more recent studies of practice
behavior, making practice assignments in terms of time practiced instead of goals
accomplished remains one of the most curious and stubbornly persistent traditions in
music pedagogy (Kostka, 2002). Music teachers more often ask students to record
practice time than they ask them to record the achievement of practice goals (Barry
&McArthur,1994),whichpromotesthenotionthatallstudentsneedtopracticea
prescribed number of minutes each day, regardless of how long it takes individuals to
accomplish what they set out to do (Duke, Flowers, & Wolfe, 1997). In fact, informal
reviews of private teachers’ instructions for practice reveal that teachers commonly
assign only what to practice and how long to practice, with little attention given to
specific proximal goals to be accomplished each day. This is in stark contrast to
assignments in many academic disciplines in school, where students are given sets of
problems to solve, chapters to read, or essays to write, and the time devoted to home-
work is determined by the time required to complete the problems, read the chapters,
or compose the essays. It seems readily accepted in other disciplines by teachers and
students alike that all students will not devote the same amount of time to assign-
ments, because individual learners work at different rates and different learners will
not require the same amount of time to complete each assignment. How long one
works depends on how long it takes to accomplish the assigned goals.
Although similar individual variations exist in the time required to accomplish
performance goals in music, setting daily goals according to time spent seems to
have become an accepted convention in planning music practice, most noticeably

among developing musicians. This is perhaps because of the notion that setting a
routine for practice develops habits of consistent effort or because of the belief that
daily repetition will inevitably lead advantageously to automaticity of motor skills.
But, if the efforts made in practice are generally ineffective in improving performance,
it is understandable that some learners conclude that their limited accomplishment is
not worth the time invested.
There have been few studies to date in which skilled performers’ practice behav-
iors have been observed in detail, the work of Chaffin and colleagues being the most
obvious exception. The reasons for this are understandable, because the challenges
of assessing practice behavior in a way that is systematic yet informative (beyond the
measurement of discrete variables, such as time or duration of performance episodes)
are daunting, to say the least.
The purpose of this study was to test the extent to which the quality of advanced
pianists’ performances of a difficult passage approximately 24 hr after it was introduced
could be predicted based on what the pianists did during practice on the passage. We also
set out to describe practice behaviors of the most effective learners in our sample.
Method
Participants were 17 graduate and advanced-undergraduate piano majors enrolled
in piano performance and piano pedagogy degree programs in the Sarah and Ernest
Butler School of Music at The University of Texas at Austin. We were able to iden-
tify 17 pianists who were willing to complete the research sessions.
Participants learned to play a three-measure passage from Dmitri Shostakovich’s
Concerto No. 1 for Piano, Trumpet and String Orchestra, Op. 35 on a Yamaha
Disklavier acoustic piano (see Figure 1). We chose the excerpt on the basis of its dif-
ficulty and accessibility—although it presents a number of technical challenges
to the pianist and is quite difficult to sightread at tempo, it can be learned within a
single practice session.
Upon arrival at the test location, participants were given approximately 2 min to
warm up in whatever manner they wished. At the conclusion of the warm-up period,
they were given a printed copy of the test excerpt (marked with their participant
number), an electronic metronome, and a pencil. The following instructions were
read aloud by the proctor, who remained in the room throughout all practice and test
periods:
Practice this excerpt until you feel that you have learned it well and can play it confidently
at the target tempo (120 bpm) without the metronome. Take as much time as you need.
Apencilandmetronomehavebeenprovidedifyouwishtousethemduringpractice.
When you return tomorrow, you will play this excerpt again. The purpose of this project
is to describe the changes that occur in your playing of the excerpt between today and
tomorrow.

Duke et al. / Characteristics of Practice 313
We permitted participants to practice for as long as they wished. There were no
explicit instructions concerning use of the metronome and pencil given to partici-
pants at the start of the session, and no apparent patterns were observed in the use of
these items. Some participants used the metronome intermittently throughout prac-
tice, whereas others used it only as they neared the end of practice. The majority of
participants wrote several fingerings in their scores (mostly for left-hand passages),
and only 3 of the 17 pianists made additional markings in their music (e.g., circling
notes, fingerings, or challenging transition points). When participants indicated that
they were confident they had learned the excerpt and that they could play the excerpt
at the target tempo on the following day, the proctor collected the music and
instructed the participants not to practice the excerpt (even from memory) before
returning 24 hr later. (The participants reported that they complied with our request
not to practice the passage.)
When participants returned the following day, they were read the following
instructions:
You have approximately 2 minutes to warm up as you wish. Please do not play any part
of the excerpt you learned yesterday during the warm-up.
At the end of the warm-up period, participants were given the same copy of the
music they had used during their practice session on the previous day. The following
instructions were read:
Play straight through this excerpt at the target tempo 15 times. Please do not stop during
any of your performance trials.
The proctor then played the metronome at the target tempo until the participant
began his or her first trial, at which time the metronome was turned off. The 15

performance trials were played in succession, separated by brief pauses whose dura-
tion were determined by the participants. We included 15 trials in the retention ses-
sion to provide us with enough material to make reliable discriminations among the
performers.

data from the keyboard for subsequent analysis. In addition, we converted the MIDI signal
from the retention test performances to QuickTime audio files for evaluation.
We observed all video recordings of the 17 participants’ practice sessions and
compiled the following numerical data from each session: total practice time,
number of performance trials (the number of times the pianist began playing), number of
complete performance trials (the number of hands-apart or hands-together performances
of the entire excerpt), number of correct performance trials (complete performances
of the entire excerpt at any tempo without error or hesitation), number of near-
correct performance trials (complete performances of the entire excerpt at any tempo with
only one or two minor errors or hesitations), the sum of correct and near-correct
performance trials, number of incorrect performance trials (performances of the
entire excerpt that contained errors), the percentage of complete trials that were cor-
rect (the proportion of performances of the entire excerpt that were without error or
hesitation), the percentage of complete trials that were correct and near-correct (the
proportion of performances of the entire excerpt that were without error or hesita-
tion plus those with only one or two minor errors or hesitations), and the percentage
of all trials (including incomplete trials) that were correct. From the retention tests,
we recorded the number of trials out of 15 attempts that were correct, the number of
trials that were near-correct, and the sum of the correct and near-correct trials. Note
that the correct and near-correct trials in these analyses were defined only in terms
of pitch and rhythm accuracy. Interjudge reliability for our assessments of correct
and near-correct trials was .96.
After recording the numerical data, we observed the video recordings again in an
effort to characterize further the features of each participant’s practice procedures. We
wrote explicit descriptions of the practice behaviors that appeared rather consistently
throughout each participant’s practice session. When there were discrepancies among
our descriptions, we arrived at consensus after viewing the tapes together to clarify one
another’s observations. Thus, the descriptors of practice presented in Table 1 represent
only those characteristics that were agreed upon by all three authors.
We independently ranked the audio recordings of the retention test performances,
taking into account the tone, character, and expressiveness of the performances. This
ranking procedure permitted a more encompassing evaluation of the retention test
performances, beyond the simple counting of correct and near-correct trials. The 17
QuickTime audio files were assigned random ID numbers that differed from the
sequential numbering of the practice videotapes and were placed in an otherwise-
empty folder on an Apple Macintosh computer screen. Clicking on a given icon ini-
tiated playback of the participant’s 15 retention test performances. We listened

individually to the recordings over high-quality loudspeakers. Our task was to rank
the participants from best to worst in terms of overall performance quality across the
15 trials in the retention test. This procedure for evaluating multiple music perfor-
mances proved quite advantageous, as it combined unlimited opportunities for
rehearing, ease in hearing performances in juxtaposition, and the ability to order on
the computer screen the icons representing the performers’ retention tests.
Agreement across our rankings was moderately high and certainly acceptable for the
purposes of our investigation, Kendall’s W= 0.83, p< .001.
Results
We report the characteristics of each participant’s practice session in Table 1.
Participants’ data are ordered based on the mean of our rankings of the retention test
performances, which are positively correlated, but not perfectly correlated, with the
total number of correct and near-correct repetitions in the 15 retention test trials, r=
–.79, p< 001. The size of this correlation (64% shared variance between rankings of
overall performance quality and counts of correct and near-correct trials) provides
some indication of the extent to which performance quality variables other than
correct notes and rhythmic precision affected our ranking judgments.
We per f o rmed b i va r i ate cor r e latio n s betwe e n e ach of th e varia b les in th e t a ble and
the participants’ rankings. These results are reported in the bottom row of Table 1. In
addition to the understandably high correlation between the mean judge ranking and
the sum of correct and near-correct trials in the retention test, there were significant
correlations between the pianists’ rankings and the following: the number of complete,
incorrect performance trials, r=.48,p=.05;thepercentageofallcompletetrialsthat
were correct, r=–.71,p=.001;thepercentageofcompletetrialsthatwerecorrectand
near-correct, r=–.64,p=.006;andthepercentageoftotalperformancetrials(includ-
ing incomplete trials) during practice that were correct, r=–.51,p<.04.
It seems equally important to point out the variables that were not related signif-
icantly to participants’ retention test ranks: the total time practiced, r= .18, p> .49;
the total number of performance trials, r= .12, p> .65; the total number of complete
trials, r= .02, p> .93; and the total numbers of correct and near-correct trials, r=
–.15, p> .56. This seems an indication that the nature of the practice defined in our
observations was more determinative of retention test performance than was the
amount of practice. We found that the three participants whose retention tests earned
the highest ranks were clearly superior to the next-highest-ranked participants (data
for those three participants appear above the line in the table). The retention test per-
formances by these three pianists were distinguished from the performances of the
other participants by a more consistently even tone, greater rhythmic precision,
greater musical character (purposeful dynamic and rhythmic inflection), and a more
fluid execution.

This finding led us to begin our practice session observations with the sessions of
these 3 pianists in an effort to identify the elements that best characterized their
work. We reached consensus on the following eight elements, all of which except
Item D below appeared in the 3 top-ranked pianists’ practice sessions; Item D was
in evidence in 2 of the top 3 pianists’ sessions. Letter designations below correspond
to those in Table 1. The combination of practice strategies that characterized the
practice sessions of the top-ranked pianists was clearly absent in the sessions of
the other pianists, although many of the 14 lower-ranked pianists included some of the
strategies used by the top 3.
A. Playing was hands-together early in practice.
B. Practice was with inflection early on; the initial conceptualization of the music was
with inflection.
C. Practice was thoughtful, as evidenced by silent pauses while looking at the music,
singing/humming, making notes on the page, or expressing verbal “ah-ha”s.
D. Errors were preempted by stopping in anticipation of mistakes.
E. Errors were addressed immediately when they appeared.
F. The precise location and source of each error was identified accurately, rehearsed,
and corrected.
G. Tempo of individual performance trials was varied systematically; logically under-
standable changes in tempo occurred between trials (slowed down enough; didn’t
speed up too much).
H. Target passages were repeated until the error was corrected and the passage was
stabilized, as evidenced by the error’s absence in subsequent trials.
The following three observations also were made based on the three top-ranked
pianists’ practice sessions. We list them separately here because they are not practice
strategies but are nevertheless descriptive of the sessions we observed.
I. When tempo was changed, the first trial at the new tempo was nearly always accu-
rate.
J. After the initial learning phase, errors were only intermittent; there were no per-
sistent errors.
K. At least 20% of all starts were complete, correct performances, although not nec-
essarily at the target tempo of 120 bpm.
Discussion
Our data describe the practice behaviors of multiple, advanced-level performers
learning the same excerpt. This is one of the few reported examples of research that
defines the characteristics of effective practice based on the observed behaviors of
multiple advanced performers with varied levels of practice skill. Our findings illu-
minate some of the important aspects of practice that differentiate more and less able
practicers, as determined by their performances 24 hr after practice.

Our results show that, among our sample of performers, the strategies employed
during practice were more determinative of their retention test performances than
was how much or how long they practiced. It seems particularly notable that total
time and total number of performance trials were unrelated to the quality of the
retention test performances and that the best-performing pianists took no less time
to learn the passage than did the other pianists. This seems to contravene the notion
that the pianists who performed best on the retention test were able to learn the pas-
sage more quickly and more easily than the others. A more accurate summary of
what took place is that the top-ranked pianists learned the excerpt differently from
the other pianists.
The most notable differences between the practice sessions of the top-ranked
pianists and the remaining participants are related to their handling of errors. The
observations labeled F, G, and H in Table 1 were present in the sessions of all three
of the top-ranked pianists, but they appeared in few of the other pianists’ practice
sessions (none of the other pianists demonstrated all three of these characteristics).
The three characteristics are as follows:
F. The precise location and source of each error was identified accurately, rehearsed,
and corrected.
G. Tempo of individual performance trials was varied systematically; logically under-
standable changes in tempo occurred between trials (slowed down enough; didn’t
speed up too much).
H. Target passages were repeated until the error was corrected and the passage was
stabilized, as evidenced by the error’s absence in subsequent trials.
Thus, it seems that the actions taken subsequent to the discovery of errors were
major determinants of the effectiveness of practice. It was not the case that the top-
ranked pianists made fewer errors at the beginning of their practice sessions than did
the other pianists. But, when errors occurred, the top-ranked pianists seemed much
better able to correct them in ways that precluded their recurrence. This is an
extremely important point—that the effective handling of error correction led to a
higher proportion of correct, complete performance trials during practice.
The most effective way that the participants corrected errors was by making judi-
cious changes in performance speed that facilitated the maintenance of accuracy fol-
lowing the correction of a given error. Of course, there were other methods of
decontextualization, in addition to tempo change, that appeared among the strategies
employed by these performers (e.g., playing shorter passages, playing hands sepa-
rately), but the method of varying tempos was a distinctive feature of the top-ranked
pianists’ approaches. In fact, two of the top-ranked pianists made alterations in their
performance tempos that preempted errors before they occurred (labeled Item D in
Table 1). In other words, after a given error was discovered, these two pianists tended
to hesitate in subsequent trials as they approached the location of the error, often
slowing the tempo (without stopping) to a point at which the playing could continue
accurately past the location where the error had occurred in a preceding trial.

These results point to the importance of developing in young musicians effective
approaches to correcting errors—procedures that preclude errors’ persistence.Yet, it
is rare in published methods to see examples of systematic instruction in problem
solving and error correction, even though devising solutions to problems is one of the
central features of learning. It is generally not the case that experts (in any discipline)
simply avoid making mistakes when they are learning something new, but experts
correct their mistakes efficiently and effectively. Thus, it seems that error correction
should be a prominent part of novices’ instruction and that the most appropriate goal
for young learners is not that they play their instruments for 30 minutes a day but
that they skillfully identify and systematically address the mistakes that are an
inevitable part of learning.
It is understandable that many students of music are of the mind that their primary
goal is to avoid making mistakes, and most young players are not privy to what goes
on in experts’ individual practice sessions, including their own teachers’ practice ses-
sions. These same students may come to believe that a major difference between them
and their teachers is that their teachers seldom make mistakes at all, when in fact all
learners, including experts, make mistakes as they take on new challenges, learn new
repertoire, encounter new problems, and teach new students. Experienced musicians’
expertise is characterized by their ability to deal with mistakes and solve knotty prob-
lems in ways that maximize efficiency and lead to lasting solutions.
There is no doubt that most students have heard their teachers demonstrate good
playing, but it is probably also true that few have observed their teachers encounter-
ing performance problems and advantageously addressing them. If there is broad
agreement that providing good models is an effective strategy for learning, then why
are there so few available models of effective practice? It is clear that this question
deserves considerable attention in the future.
