Con

1. Limited Genre Selection: Synthesia primarily offers classical and traditional songs, which might not cater to users interested in contemporary or various music genres, potentially limiting its appeal to a wider audience.

2. No Original Composition Tools: Synthesia lacks features for composing or creating original music, making it less suitable for users looking to compose or produce their own songs.

3. Dependency on MIDI: Synthesia's functionality relies heavily on MIDI files. Users without access to quality MIDI files for the songs they want to learn may find the app less useful, as it does not provide a large built-in library of songs.
