Approaching new piano literature: composition and interpretation of four piano etudes

Modeling Piano Interpretation Using Switching Kalman Filter

An approach of parsing piano music interpretation is presented. We focus mainly on quantifying expressive timing activities. A small number of different expressive timing behaviors (constant, slowing down, speeding up, accent) are defined in order to explain the tempo discretely. Given a MIDI performance of a piano music, we simultaneously estimate both discrete variables that corresponds to th...

The Elbow Piano: Sonification of Piano Playing Movements

The Elbow Piano distinguishes two types of piano touch: a touch with movement in the elbow joint and a touch without. A played note is first mapped to the left or right hand by visual tracking. Custom-built goniometers attached to the player's arms are used to detect the type of touch. The two different types of touches are sonified by different instrument sounds. This gives the player an incre...

Piano Hammer-String Interaction

A hammer-string interaction for bass notes is investigated and the problem what can cause the hammer to rebound is clarified. For a linear elastic hammer interacting with a long flexible string the exact solution of the equation describing the hammer motion is derived. It was shown that in some cases no reflected wave is needed to assist the hammer for going away from the string. The numerical ...

The Gesturally Extended Piano

This paper introduces the Gesturally Extended Piano—an augmented instrument controller that relies on information drawn from performer motion tracking in order to control real-time audiovisual processing and synthesis. Specifically, the positions, heights, velocities, and relative distances and angles of points on the hands and forearms are followed. Technical details and installation of the tr...
