Turn it on

Open Preferences from the menu at the top right and turn on Solfège (movable do).

The key signature decides which note is do, so a passage that changes key keeps reading correctly.

Minor keys read with the tonic as la. The key can't be set by hand.

In English, syllables read do re mi fa so la ti, with altered vowels for chromatic notes. The spelling follows the app's language.
