Suspensions

Here's my dumb question: Okay I missed the day suspensions were introduced and I've been a bit confused ever since, which notes are you looking at to find the interval for the suspension? Are you looking at the other note in the bass cleff (the presumed tenor) or soprano/'alto' note?

(I usually just found whatever one worked and went with it but it'd be nice to know if there's a rule about that I've been retarded about.)

The interval names for suspensions are determined from the bass note that is sounding at the time the dissonance occurs. Another words if you have the preparation which is consonant and it holds over into the next beat where it forms a 9, 7, or 4th with the bass note and then it moves down by step to a 8,6, or 3 you have a suspension. The numbers represent the interval above the bass note to the note that is creating the dissonance and resolving. If the suspension is in the bass voice it is a 2 -3 because the bass will hold over and clash with a note in S, A, or T in the interval of a second and then resolve down to form a 3rd with the same pitch it was clashing with.
This would be easier to examine in a piece of music than write about, but I hope this helps.
