Before you start
What is MusicXML?
An editable score file containing notes, lyrics and chords. You can edit and play it in Akbopro.
What if conversion makes a mistake?
Compare with the original and correct misread content. Image clarity and layout affect recognition, so review the result.
Can I turn a melody into a choir score?
A reviewed melody and chords can become a four-part draft. Listen and edit to refine it.
What does practice sound like?
Compare four arrangement styles with instrumental playback or English and Korean singing. Switch to the melody alone or individual vocal parts. Saved scores can generate singing audio from Korean or English lyrics. Piano and choir pitch guides are also available. Microphone analysis runs on your device after you start it.
