A computing device may receive, via an interface of the computing device, a selection of music. In addition, the computing device may generate a first representation of the music, wherein the first representation may include symbols, and wherein the first representation of the music does not include clef, staff, or notes. The computing device may generate a second representation of the music, wherein the second representation of the music may include the symbols overlayed on notes. The computing device may generate a third representation of the music, where the third representation of the music may include the symbols overlayed on the notes and clef and staff. The computing device may generate a fourth representation of the music, where the fourth representation of the music may include the notes, clef, and staff, and where the fourth representation of the music does not include the symbols.

Audio inputs receive in real time a live session of a plurality of a series of sounds produced by a respective plurality of musical instruments or human voices. One or more processors execute instructions to receive in real time the live session, select a respective level of musical difficulty of the piece of music for the plurality of the series of sounds produced by the musical instruments or human voices, adapt in real time the plurality of the series of sounds according to the selected level of musical difficulty of the piece of music, and orchestrate in real time the adapted plurality of the series of sounds into a musical arrangement. An audio output transmits in real time the musical arrangement.

Systems, devices, media, and methods are described for presenting a tutorial in augmented reality on the display of a smart eyewear device. The system includes a marker registration utility for setting a marker on a musical instrument, a localization utility, a virtual object rendering utility for presenting virtual tutorial objects on the display near the instrument, and a hand tracking utility for tracking the performer's finger locations in real time. The virtual tutorial objects, in one example, includes graphical elements presented on a virtual scroll that appears to move toward the instrument at a speed correlated with the song tempo. The hand tracking utility calculates a set of expected fingertip coordinates based on a detected hand shape.
