Synthesia

Synthesia is a software program that allows users to create piano tutorials from MIDI files. It visualizes music by displaying falling colored keys on a virtual piano keyboard, making it easier for beginners to learn and play songs. The software can be used for educational purposes, entertainment, or to share musical creations.

The core functionality of Synthesia involves importing MIDI data, which contains the musical notes, timing, and velocity information for a piece of music. The program then renders this data in real-time, showing which keys are to be pressed and when. Users can customize the appearance of the falling keys, the piano itself, and the overall visual experience. It also offers features such as pitch and tempo control, and the ability to record and export performances as video.

Synthesia is widely used by hobbyist musicians and piano learners who find the visual representation of music a helpful learning aid. It is available for Windows, macOS, and iOS devices. The software's accessibility and engaging interface have contributed to its popularity in the online music learning community, with many users sharing their Synthesia-generated videos on platforms like YouTube.
