Piano study, practice, and creation
Ledutu helps piano learners move from song ideas to real practice
Ledutu is a bilingual piano learning platform for Vietnamese musicians who want practical jazz piano resources without jumping between separate tools. It brings together original piano sheet music, searchable song chords, visual chord and scale references, browser-based practice tools, ear-training exercises, and a MIDI Visualizer for creating piano roll videos. The experience is built around the way pianists actually study: find a song or arrangement, understand the harmony, transpose it when needed, train the ear, improve timing, and turn a MIDI performance into material that can be reviewed, taught, or shared.
