Count the interval — intermediate

Widen the range up to the sixth: hear it, reveal it on the staff and count the names to find the number.

1. Step 1Listen to the ascending interval from C4: now the fifth and the sixth come in too.
2. Step 2Reveal the notes on the staff, always without accidentals in the key of C.
3. Step 3Count the note names including both endpoints to get the number (C to G: C-D-E-F-G, a fifth).
