ArmKeyBoard: A Mobile Keyboard Instrument Based on Chord-scale System and Tonal Hierarchy
نویسندگان
چکیده
Traditional keyboard instruments, with their sheer size and key anisotropy, although are versatile in musical expression, are difficult to learn and inconvenient to carry around; and its linear layout somewhat rules out the musical possibility of non-linearity. Trying to address this, we design a keyboard with both linear and non-linear layouts based on chord-scale system and tonal hierarchy. Several flipping mechanisms and mapping algorithms are devised to try to equip this small portable keyboard with as much musical expression capability as possible as compared with a traditional keyboard. Evaluation results show that both the musical outcome and user experience of ArmKeyBoard are satisfactory, although people may still prefer a linear keyboard to a non-linear one.

Automatic Key Partition Based on Tonal Organization Information of Classical Music
Key information is a useful information for tonal music analysis. It is related to chord progressions, which follows some specific structures and rules. In this paper, we describe a generative account of chord progression consisting of phrase-structure grammar rules proposed by Martin Rohrmeier. With some modifications, these rules can be used to partition a chord symbol sequence into different...
متن کاملImproving Audio Chord Transcription by Exploiting Harmonic and Metric Knowledge
We present a new system for chord transcription from polyphonic musical audio that uses domain-specific knowledge about tonal harmony and metrical position to improve chord transcription performance. Low-level pulse and spectral features are extracted from an audio source using the Vamp plugin architecture. Subsequently, for each beat-synchronised chromagram we compute a list of chord candidate...
متن کاملA Model for the Perception of Tonal Melodies
This paper presents a concise description of OPTM, a computational model for the On-line Processing of Tonal Melodies. It describes the processes a listener executes when transforming a tone sequence into a tonal melody. The model is based on the assumption that a tone sequence is represented in terms of a chord progression underlying the sequence. Chord tones are directly coded in the harmonic...
متن کاملA Graphical Model for Chord Progressions
Chord progressions are the building blocks from which tonal music is constructed. Inferring chord progressions is thus an essential step towards modeling long term dependencies in music. In this paper, a distributed representation for chords is designed such that Euclidean distances roughly correspond to psychoacoustic similarities. Graphical models observing chord progressions are then compare...
متن کاملQuantification of the hierarchy of tonal functions within a diatonic context.
Listeners rated test tones falling in the octave range from middle to high C according to how well each completed a diatonic C major scale played in an adjacent octave just before the final test tone. Ratings were well explained in terms of three factors. The factors were distance in pitch height from the context tones, octave equivalence, and the following hierarchy of tonal functions: tonic t...
