Melisol listens while you sing. Nothing is recorded or sent.What Melisol sends, and when


Play the answer on your guitar, piano or another instrument, or on a MIDI keyboard plugged into your phone.


A right answer turns green, with one plain line on why it sounded that way.


Short levels, one world at a time: the gap between two notes, a note's place in the scale, chords and tunes. Each level says what it trains and what comes next, in plain words.
Notes are numbers, not sheet music.




Every day there is a new Daily Tune. Sing it back, tap its notes, or tap its shape: up, same or down. Share your result without giving the tune away.

Sing to fly Sol through the gates of a tune. Your voice is the line Sol follows.


Sol sings a short call and you echo it. Each clean echo brings in another player, until the whole band is playing.


Hold one steady note while Sol sings a tune, and hear the two fit together. Harmony needs headphones.


Test your range and see it on a card. Voice types are a rough guide, and your range can grow.






Play a round, then send the link. You both get the same questions. No accounts, no names. A challenge link works for 14 days.
Any name you see is a label you added on your own phone.


Pick how many days a week you want to practise. Today shows your week, and Sol keeps you company in every session.
Practising earns XP, and each new level brings something: a dance for Sol, a new sound, an Echo Jam beat, or something new in Sol's sky.
