Musicca review

Musicca is a free website built to teach music theory, and it says it will stay free. Its exercises cover notes, rhythms, intervals, chords, scales and key signatures, with game elements added to keep practice moving, and short lessons explain the staff, clefs, accidentals, intervals, chords, scales and keys. Around those sit virtual instruments, from piano and guitar to violin and drum kit, plus tools like a chord finder, scale finder, circle of fifths, metronome, tuner and printable staff paper. Teachers can create classes for free and follow each student's progress. Musicca says millions of people from more than 150 countries use it every month. Creating a free account removes ads and opens all content. The lessons stop at fundamentals and there is no offline app, so it suits beginners and classroom practice more than advanced study.
