Conference Paper
Full-text available
Percussion robots have successfully used a variety of actuator technologies to activate a wide array of striking mechanisms. Popular types of actuators include solenoids and DC motors. However, the use of industrial strength voice coil actuators provides a compelling alternative given a desirable set of heterogeneous features and requirements that...
Conference Paper
Full-text available
Human motion associated with a percussion performance is incredibly complex and filled with subtle nuances that span timing, dynamics, and timbre. Recreating such a performance robotically or through synthesis requires a systematic method of data acquisition and analysis that leads to a concise set of parameters to drive multi-dimensional models. B...

Phenology is the study of periodic biological processes, such as when plants flower and birds arrive in the spring. In this paper we sonify phenology data and control the sonification process through a tangible interface consisting of a physical paper map and tracking of fiducial markers. The designed interface enables one or more users to concurre...

Full-text available
The study of periodic biological processes, such as when plants flower and birds arrive in the spring is known as Phenology. In recent years this field has gained interest from the scientific community because of the applicability of this data to the study of climate change and other ecological processes. In this paper we propose the use of tangibl...

Hyper-instruments extend traditional acoustic instruments with sensing technologies that capture digitally subtle and sophisticated aspects of human performance. They leverage the long training and skills of performers while simultaneously providing rich possibilities for digital control. Many existing hyper-instruments suffer from being one of a k...
Conference Paper
Full-text available
The radiodrum is a virtual controller/interface that has existed in various forms since its initial design at Bell Laboratories in the 1980's, and it is still being developed. It is a percussion instrument, while at the same time an abstract 3D gesture/position sensor. There are two main modalities of the instrument that are used by composers and p...

The goal of this research is to collaborate with a number of different artists to explore the capabilities of robotic musical instruments to cultivate new music. This paper describes the challenges faced in using musical robotics in rehearsals and on the performance stage. It also describes the design of custom software frameworks and tools for the...
Article
Full-text available
Timing is perhaps the most fundamental aspect of music, and visualization tools can help in formulating hypotheses and exploring questions regarding musical timing. We present a series of novel graphical representations of musical timing, generated by computer from signal analysis of audio recordings and from listeners' annotations collected in rea...
Conference Paper
Full-text available
The majority of existing research in Music Information Re- trieval (MIR) has focused on either popular or classical mu- sic and frequently makes assumptions that do not generalize to other music cultures. We use the term Computational Eth- nomusicology (CE) to describe the use of computer tools to assist the analysis and understanding of musics fro...
Conference Paper
As artists working in public art and media, we have repeatedly found that the usual parameters and characteristics for a work of art have to be heavily modified to be successful in an ambient environment. Art does not normally strive to be innocuous or inconspicuous; however every artist who does public art quickly learns to deal with the impact of...
Article
Full-text available
Physical modeling has proven to be a successful method of synthesizing highly expressive sounds. However, providing deep methods of real time musical control remains a major challenge. In this paper we describe our work towards an instrument for percussion synthesis, in which a waveguide mesh is both excited and damped by a 2D matrix of forces from...

Abstract. John Blacking said “The main task of ethnomusicology is to explain music and music making with reference to the social, but in terms of the musical factors involved in performance and appreciation” (1979:10). For this reason, research in ethnomusicology has, from the beginning, involved analysis of sound, mostly in the form of transcripti...
Article
Full-text available
Physical modeling is a proven technique for creating sounds with rich expressive potential, but the state of the art in control does not offer access to the whole of this potential. New developments in modeling algorithms are typically presented with single-point, idealized excitations where more complex ones would add vitality to the sounds produc...

We present the results of our ongoing project researching a tighter coupling between computer and performer. The audio-input radio drum is presented, a simplification of the original apparatus that provides superior latency and res-olution. Different demodulation schemes for the amplitude modulated input signals are discussed. Techniques to analyze...
Article
This article describes systems for capturing gestures from a performing artist playing North Indian instruments. Modified traditional instruments use sensor technology and microcontrollers to digitize performance, enabling a computer to synthesize sound and generate visual meaning. Specifically, systems were built to capture data from three traditi...
Conference Paper

Drum controllers designed by researchers and commercial companies use a variety of techniques for capturing percus- sive gestures. It is challenging to obtain both quick response times and low-level data (such as position) that contain ex- pressive information. This research is a comprehensive study of current methods to evaluate the available stra...

There are many techniques available to capture the gestures of a performer. By utilizing digital signal processing and machine learning techniques we are able to capture, process and classify signals in real-time in order to provide data for use by musicians in a performance context. A common technique that achieves similar results is the use of se...

We present a flexible and inexpensive system for analyzing gesture data in a computer. Several basic data reductions are introduced, and the tradeoff between latency and reliability is discussed. An example of the application of this technology to musical performance is presented via the example of the radio drum, a musical controller that produces...
Article
Full-text available
The use of computers in live performance has resulted in a situation in which cause-and-effect has effectively disappeared, for the first time since music began. Once we started to use computers in live performance – to interpret gestures and generate sound as a result – the age-old relationship between gesture and result became so blurred as to be...
Article
Full-text available
We propose that the phrase repetitions in the canon per tonos from J.S. Bach's Musical Offering are not recognized by listeners as being successively upward. We examine possible causes for this effect and suggest that it may be due to Bach's use of chromatic harmony. To test this hypothesis, we conducted an experiment in which one group of listener...
Conference Paper
Full-text available
We describe the ways in which we are analyzing gestural data as if they were an audio signal, and applying this technique to the radio drum, a novel three-dimensional controller that one of the authors uses regularly for concert performances. The radio drum uses capacitive sensing; a radiofrequency voltage source is conducted from the performer's m...
Article
This paper examines the potential problems that “too much” technology in musical performance can create. In developing very powerful computer‐assisted instruments, and in decoupling the sound production from the gesture, issues of what performance is really about start to surface. This is a relatively recent problem, because it is only in the last...

The goal of my research is to understand the nuanced range of human motion in the context of percussion performances and translate it into a robotic system using innovative technologies and algorithms. The system design will serve as a pragmatic multi-dimensional platform for further study with an emphasis on timing, dynamics, and timbre that are driven by appropriately constrained stochastic processes.
