Try www.good-ear.com for intervals, your program is probably better, but that will do the job.... Then just remember that 4ths and 6ths feel as though they should go down to finish, 2 is dissonant, as is 7, and then remember 3 and 5 :)
Well.... that's what I did.
Then you get onto the harder task of chromatic intervals :eek:
