and absolute time (a piano-roll representation), but not in musical terms, with spelling distinctions (e.g., A versus G ) and quantized meter. To complete the transcription process, one would need to convert the piano-roll representation into a properly formatted and musically meaningful musical score

We investigate the problem of modeling sym-bolic sequences of polyphonic music in a com-pletely general piano-roll representation. We introduce a probabilistic model based on dis-tribution estimators conditioned on a recur-rent neural network that is able to discover temporal dependencies in high

spectrograms and piano roll representations to solve audio interpolation and restoration problem. The model incorporates temporal and harmonic information from an approximate musical score (not necessarily belonging to the played piece), and spectral information from isolated piano sounds. The performance

of (complex) musical events perceived as wholes within coherent musical streams- the musical surface is not merely an unstructured sequence of atomic note events, such as score notes or a piano-roll representation. Additionally, it is maintained that the emergence of the musical surface involves rather

), (b) the object model (e.g., that it is a grand piano), or(c) a representation intermediate between (a) and (b) consisting of convex or singly concave components of the object, roughly corresponding to the object’s parts. Subjects viewed pictures with half their contour removed by de-leting either (a

Automatic music transcription (AMT) is the process of converting an acoustic musical signal into a symbolic musical representation such as a MIDI piano roll, which contains the pitches, the onsets and offsets of the notes and, possibly, their dynamic and source (i.e., instrument). Existing

Abstract—Scatterplots remain one of the most popular and widely-used visual representations for multidimensional data due to their simplicity, familiarity and visual clarity, even if they lack some of the flexibility and visual expressiveness of newer multidimensional visualization techniques

-Negative Matrix Factorisation to the task of transcription—where a basis for each note on the fretboard is learned and fitted to a magnitude spectrogram of the hexaphonic recording, which then undergoes a nonlinearity generating a piano roll representation of the music performance.

-dimensional geometric objects (consider the piano-roll representation), but the definition of similarity varies considerably within the framework. We scrutinise these frameworks trying to find common, relevant properties that either inhibit or boost the effectiveness of the methods. Although the edit-distance framework

Standard signal processing techniques based on the short time Fourier transform are used to create a time-frequency representation of the signal
