Intervals lesson 8.3

[joewmilos]

I'm no expert, which is why I'm doing the beginners course, so someone please correct me if Im wrong. If we are in the key of C (which the lesson is) and the question is C>G descending, I believe that's still a fifth, not a fourth as the lesson teaches. Could be wrong, any info would be appreciated.

Hi,

C and G are 5 semitones apart, and that makes a perfect 4th regardless of whether the interval is played upwards or downwards.

I think it is a perfect fifth going upward (7 semitones between C and G) and a perfect fourth going downward (5 semitones between G and C, which is also 12 - 7).

@Doomro: The post was about C-G descending (G is the bass), not ascending
