The present invention relates to a music chords conversion device. The device is used for providing instant representation showing conversion or correlation of major chords to minor chords and vice versa. The device can come in two variants (1) a physical device (2) a digital device. The physical device has a chords conversion component and a minor chords component wherein the minor chords component is configured to slide into the chords conversion component through a cut-out opening. The minor chords can be correlated to the major chords and displayed in a viewing region of the chords conversion component. The digital device includes a memory for storing the chords conversion and also includes a digital display for displaying the converted minor and major chords.

An information processing method is an information processing method including generating an output track by using an input track including a plurality of first information elements provided over a certain period or a certain section and a learned model (21), in which the output track includes a first track that is a same track as the input track or a changed track, and a second track including a plurality of second information elements provided over the certain period or the certain section, and the learned model (21) is a learned model generated by using training data so as to output output data corresponding to the output track when input data corresponding to the first track is input.

A strainer system includes an adjustable slide assembly that can be used as a strainer side assembly or a butt side slide assembly for tensioning a snare that will not detune due to sympathetic vibrations. The strainer system may also be configured to easily control the amount of snare contact with the bearing edge on both the strainer side and the butt side of the shell body.

Embodiments of the present invention provide methods, computer program products, and systems to for automatic key transposition. Embodiments of the present invention can be used to determine compatibility between a known melody capable of being generated by a pitch generation system and a first performance profile associated with a first performer that performs in conjunction with the pitch generation system. Embodiments of the present invention can be further used to determine an appropriate key to update one or more pitches associated with the known melody, to be generated by the pitch generation system during the performance by the first performer, based on the compatibility between the first performance profile and the known melody.

The present disclosure presents a novel approach to automatic transcription of piano music in a context-dependent setting. Embodiments described herein may employ an efficient algorithm for convolutional sparse coding to approximate a music waveform as a summation of piano note waveforms convolved with associated temporal activations. The piano note waveforms may be pre-recorded for a particular piano that is to be transcribed and may optionally be pre-recorded in the specific environment where the piano performance is to be performed. During transcription, the note waveforms may be fixed and associated temporal activations may be estimated and post-processed to obtain the pitch and onset transcription. Experiments have shown that embodiments of the disclosure significantly outperform state-of-the-art music transcription methods trained in the same context-dependent setting, in both transcription accuracy and time precision, in various scenarios including synthetic, anechoic, noisy, and reverberant environments.

The invention disclosed herein comprises a method for visually representing music to be played on a musical instrument by providing a tablature staff which is divided into individual measures by segmenting the tablature staff with measure lines. Each measure is then further divided into proportional time subdivisions using subdivision lines. Alphanumeric notes are then printed between these subdivision lines on the tablature staff, wherein each alphanumeric note represents a tone to be played on a musical instrument and wherein the duration of each alphanumeric note is indicated by the number of time subdivisions within a measure and its corresponding font size.
