The Flamenco Tutor app is a collaborative project with Flamenco dancer Niño de Los Reyes and percussionist Sergio Martinez that helps dancers configure their own music pieces for their choreographies and helps musicians learn Flamenco comping and composition. The app offers recordings of multiple alternate takes in different Flamenco music styles. Some features include customization by sections that can be looped, instruments that can be selected and muted, and tempo that can be altered. Users will also find musical and textual notation explaining the content, as well as instructional videos and practice exercises.
Here is a looped example of a verse in the Soleá por bulería style and a screenshot of the user interface. Please note that the channel count, Channels Playing, goes from 0 to 4 because what is actually played is not only one WAV or MP3 file but a stream of 4 channels of synchronized audio tracks that can be soloed or muted in the app and on this website. The right side of the user interface shows the structure of the composition with sections that can be repeated or reshuffled by dragging. A random button will shuffle each section according to some rules that musically make sense (e.g., transitions are respected):
