Intervals: 4ths from short keys (target time: 5 min. or less)

Name the P4th above and below the marked key.

All marked keys have an accidental in their name. To determine the P4 above and below, temporarily drop the accidental. Determine the 4ths around the natural-key name. Then re-apply the accidental.

For example:

• Given the marked key is Gb.
• Temporarily think in terms of G natural: the 4th below is D and the 4th above is C.
• Re-apply the accidental: the 4th below Gb is Db; the 4th above is Cb.

Repeat this quiz as many as 99 times. The order of questions will vary, since questions are randomly drawn from a question pool.
