Music transcription consists in transforming the musical content of audio data into a symbolic representation. The objective of this study is to investigate a transcription system for polyphonic piano. The input to this system consists in piano music recordings stored in WAV files, while the pitch of all the notes in the corresponding score forms the output. The proposed method focuses on tempo...

The relationship between final hammer velocity and maximum amplitude of radiated piano sound was investigated. Piano tones with varying hammer velocities were produced by a computer-monitored acoustic piano containing optical sensors and solenoids, and the sounded tones were recorded and digitized for analysis. Maximum amplitudes over the duration of the sounded tones were linearly proportional...

We present here three developments for the Commuted Piano Synthesis model described more fully elswhere in these proceedings [3]: (1)a theoretical foundation and calibration scheme for the required linearized piano hammer system; (2) a simple algorithmic synthesis approach for the commuted soundboard impulse response, eliminating the need for any wave table memory; and (3) a calibration method ...

If you are in a shipwreck and all the boats are gone, a piano top...that comes along makes a fortuitous life preserver. But this is not to say that the best way to design a life preserver is in the form of a piano top. I think that we are clinging to a great many piano tops in accepting yesterday’s fortuitous contrivings as constituting the only means for solving a given problem. (Fuller 1969, ...

Measurement of pianists’ arm movement provides a signal, which is composed of controlled movements and noise. The noise is composed of uncontrolled movement generated by the interaction of the arm with the piano action and measurement error. We propose a probabilistic model for arm touch movements, which allows to estimate the amount of noise in a joint. This estimation helps to interpret the m...

This study compares affective piano performance with speech production from the perspective of dynamics: unlike previous research, this study uses finger force and articulatory effort as indexes reflecting the dynamics of affective piano performance and speech production respectively. Moreover, for the first time physical constraints such as piano fingerings and speech articulatory constraints ...

We discuss automated piano reduction from ensemble scores based on stochastic models of piano fingering and reduction process. Music arrangement including piano transcription is an important compositional technique, automation of which creates a challenging research field. As a starting point, we aim at a simple case of piano reduction which is playable and sounds similar to the original ensemb...

Piano performance involves a large repertoire of highly skilled movements. The acquisition of these exceptional skills despite innate neural and biomechanical constraints requires a sophisticated interaction between plasticity of the neural system and organization of a redundant number of degrees of freedom (DOF) in the motor system. Neuroplasticity subserving virtuosity of pianists has been do...

Computers, Mobile and other handheld devices depend largely on passwords mechanism to identify and authenticate users. Typically, passwords are strings of characters and digits. Alphanumeric passwords are convoluted to remember for users because a safe password should be long and arbitrary, however users pick short, simple, and insecure passwords. Different solutions have been proposed to aim t...

Skilled pianists were requested to interactively adjust note (i.e., key depression) durations in simple sequences, played under computer control on a digital piano, so as to sound optimally staccato (perception task) and to perform analogous sequences with staccato articulation on the same instrument as well as on a real piano (production task). The independent variables were tempo, register, a...
