About Surilo
Surilo (सुरिलो) is Nepali for tuneful. Hum the tune in your head, and Surilo helps you find its notes, its chords and where to play it. Nothing is generated: every note is one you hummed.
Free for everyone, always. No ads, no account, and your voice never leaves your device.
Your notes
Tell the app the beat of your tune, and it writes the rhythm: note values, bars and rests. Tap along to find the BPM.
How to fix notes
Drag a note up or down to fix a flat or sharp note, or tap it and use the buttons. A note far too high or low is usually the right note in the wrong octave: use ▲ Octave or ▼ Octave. Delete a wrong note and the notes next to it fill its gap. Drag a selected note's edges to change its length. Double-click an empty spot to add a note (press and hold on a phone). The grey line is your actual voice. Dashed notes (≈) are best guesses: you hummed between two notes, so the app picked the one that fits the tune. Tap one to check it. Back to my hum throws away every edit.
Note by note
with the chords aboveFix every wrong note in the editor first. The notes as you leave them become the answer key the app is graded against. Then save the hum to the Hum to Notes tests folder in Drive.
