The Multi-Tuned Piano: Keyboard Music Without A Tuning System

The Piano Music Companion

We present a system that we call ‘The Piano Music Companion’ and that is able to follow and understand (at least to some extent) a live piano performance. Within a few seconds this system can identify the piece that is being played, and the position within the piece. It then tracks the progress of the performer over time via a robust score following algorithm. The companion is useful in multipl...

Toward a Human-Centric Automatic Piano Music Transcription System

SONIC: A System for Transcription of Piano Music

This paper presents our system for transcription of polyphonic piano music – SONIC. SONIC takes an audio signal of a piano performance and tries to determine which notes were played by the performer, thus producing a list of notes and note onset times approximately matching the performance. SONIC is composed of three main parts: partial extractor, onset detector and note recognizer. We present ...

Piece Identification in Classical Piano Music Without Reference Scores

In this paper we describe an approach to identify the name of a piece of piano music, based on a short audio excerpt of a performance. Given only a description of the pieces in text format (i.e. no score information is provided), a reference database is automatically compiled by acquiring a number of audio representations (performances of the pieces) from internet sources. These are transcribed...

Infrared vs. Ultrasonic Finger Detection on a Virtual Piano Keyboard

An immaterial digital keyboard is presented, aiming at testing possibilities to substitute physical with augmented piano keys during the performance. The main effort has been made around the realization of an accurate meanwhile fast detection of the hands movement. To achieve this goal we have tested low-cost infrared as well as ultrasonic capture devices, whose current pros and cons are presen...
