Hear what changed

Hear both plays the two scales in order. First and Second replay either one. The Hear both button becomes Stop while sound loads or plays. Count the home note as 1; listen for a change at 3, 6 or 7. Some comparisons are identical.

Each scale must finish before its listening credit is earned. Stopping the second does not erase a first scale already completed. You may choose an answer while listening; Check becomes available after both have finished.

A correct answer reveals both scales in the same frames. Reveal and study lets you compare the notation without checking an answer; it does not count as a correct response. Another comparison clears the notes and starts the next pair. Each set covers 50 comparisons before repeating.
