Harmonic Interval ID

The drill below is a speed drill - use the keyboard to enter numbers more quickly! (Use minus "-" for 11 and equals "=" for 12.)

Intervals are given in half-steps (1 = half step, 2 = whole step, 3 = minor third, etc...). Click the "traditional names" button if you prefer.

Tips -- High Scores -- Comments

Greg's Tips

Each interval has its own distinct color and sound. While at first it may be useful to sing the interval and try and determine where it falls in the scale ("Is that 3-4 or 1-2?") in the end for this sort of drill it's best to try and let go of tonal references a bit and just recognize the particular qualities that each atonal interval has.

Next Steps

This transfers perfectly to music with two (or more) parts. Find music with two singers or two instruments and listen for the colors of these intervals between them. Some of my favorites are:

I might be wrong, but it really seems that occasionally only one tone plays, especially with 4ths and 5ths.

Octal -- no, inversions are treated as different intervals. Eg: if G up to C is played, only a Perfect 4th (or 5 semi-tones, depending on what mode you're in) is accepted as the answer. (If you know Forte's interval class vector approach, this is _not_ the same.)

Does this include inversions too? I.e. is a perfect 5th only G-C or can it also be C-G (which is a perfect 4th, thus causing confusion.)

Good catch whatoh and tmt -- I've fixed it and deleted impossible scores (those with an average time less than 1 second, which is the wait time between questions).

My mistake, i used the bug for level 5 -- not level 4.
