The identity of musical instruments is reflected in the acoustic attributes of musical notes played with them. Recently, it has been argued that these characteristics of musical identity (or timbre) can be best captured through an analysis that encompasses both time and frequency domains; with a focus on the modulations or changes in the signal in the spectrotemporal space. This representation ...

This report talks about monophonic musical instrument recognition using cepstral coefficients as the features.The data set comprised of 347 samples of nine musical instruments belonging to the woodwinds, brass and string families. Classification was carried out using a multinomial logistic regression model and 10-fold cross-validation was used to validate the model. Using about 0.4 seconds of a...

This paper describes the Musical Poi (mPoi), a unique sensorbased musical instrument inspired by the ancient art of Jwibulnori and Poi spinning. The trajectory of circular motion drawn by the performance and the momentum of the mPoi instrument is converted to the energetic and vibrant sound, which creates a spiritual and meditative soundscape that opens everyone up the aura and clears the mind....

Advances in computer technologies have enabled new means of musical expression with motion enabled musical instruments, which have attracted a great deal of attention. We created a new performance system that enables a dancer to make music while b-boying, which is a dance style. We implemented sensor-equipped shoes and a system that recognizes motions and that controls music. We used an impleme...

This paper explores the design process of the AlphaSphere, an experimental new musical instrument that has transitioned into scale production and international distribution. Initially, the design intentions and engineering processes are covered. The paper continues by briefly evaluating the user testing process and outlining the ergonomics, communication prototcol and software of the device. Th...

Personality traits have unique abilities to shine through every action, thought, and belief that an individual engages in. These traits, in addition other influential life experiences, shape all expressions of personality. Past publications psychomusicology suggest music listening preferences can be measured predicted by personality traits. The present study expands on these discoveries asking ...

Increasing growth and popularity of multimedia resources available on the Web brought the need to provide new, more advanced tools needed for research. However, searching through multimedia data is highly non-trivial task that requires content-based indexing of the data. My research will focus on automatic extraction of information about the sound timbre, and indexing sound data with informatio...

This paper describes the motivation and process of developing a musical instrument for an unborn child. Well established research shows a fetus in the womb can respond to and benefit from stimuli from the outside world. A musical instrument designed for this unique context can leverage the power of this interaction. Two prototypes were constructed and tested during separate pregnancies and the ...

The vBow is a haptic musical controller human-computer interface, which simulates the forcefeedback of a bow on a violin string, while driving a bowed-string physical model. It is both a musical instrument for expressing the musical gestures of a performer, and a tool for testing friction and vibration models, and the responsiveness of physical model sound synthesis.

Spectrogram is generated for musical notes, which is used to calculate the spectral, temporal and modulation features. To detect the musical instruments from polyphonic and monophonic musical notes , 23 features are analyzed . Out of 23 features 12 specific features are used to generate feature vector . Hidden Markov model (HMM) is used to calculate the conditional instrument existence probabil...
