The present work is about the synthesis of piano sound based on the grounds of physical principles. For that, rst the acoustical properties of the piano have to be understood, since the underlying physical phenomena establish the framework for the model-based sound synthesis. Therefore, the di erent parts of the piano were measured and analyzed. The groundwork of the piano model lies in the dig...

We describe a new algorithm to transcribe musical note complexes from polyphonic piano music. Our method is a spectrogram based algorithm, which uses a robust peak detection scheme and forms note complexes by multiple sample conditional probability in the context of a time-frequency based finite state space approach, where note onsets are determined implicitly by changes in subharmonics. This p...

This paper provides an overview on the advances of music information retrieval in symbolic representation of music. Such musical aspects as key, tonality, bass, melody, dynamics, rhythm and patterns are considered as foundation for visualizing systems for the piano stream in classical music. The paper then describes the proposed visualizing system and Malinowski’s music animation machine. It la...

Local scouring in the downstream of hydraulic structures is one of the important issues in river and hydraulic engineering, which involves a lot of costs every year, so the prediction of the rate of scour is important in hydraulic design. Side weirs are the most important of hydraulic structures that are used in passing flow. This study investigate the scouring due to falling jet from side weir...

Here we propose a score-informed monaural source separation system to extract every tone from a mixture of piano tone signals. Two sinusoidal models in our earlier work are employed in the above-mentioned system to represent piano tones: the General Model and the Piano Model. The General Model, a variant of sinusoidal modeling, can represent a single tone with high modeling quality, yet it fail...

When participants are presented simultaneously with spoken language and a visual display depicting objects to which that language refers, participants spontaneously fixate the visual referents of the words being heard [Cooper, R. M. (1974). The control of eye fixation by the meaning of spoken language: A new methodology for the real-time investigation of speech perception, memory, and language ...

A new method is presented for extracting the musical key from raw audio data. The method is based on the extraction of chromagrams using a new approach for tonal component selection taking into account auditory masking. The extracted chromagrams were used to train three key profiles for major and three key profiles for minor keys. The three trained key profiles differ in their temporal weightin...

A study is reported investigating the relationship between modality (major/minor) and dynamics (piano/forte) on four affects – as evident in the content of musical lyrics. Forty solo vocal works were sampled: 10 in the major mode with a loud (forte) dynamic level, 10 in the major mode with a quiet (piano) dynamic level, 10 in the minor mode with a loud dynamic level, and 10 in the minor mode wi...

This paper presents the results of a study of piano pedalling techniques on the sustain pedal using a newly designed measurement system named Piano Pedaller. The system is comprised of an optical sensor mounted in the piano pedal bearing block and an embedded platform for recording audio and sensor data. This enables recording the pedalling gesture of real players and the piano sound under norm...

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...
