I've always wanted perfect pitch. As a good (great?!!) singer, an average piano player and a below average accordionist, having perfect pitch would make my life so much easier.
I've started using this Free Interval Online Ear Trainer. I'm not perfect yet, but for the first time in my life I know what a tritone sounds like!
There are other helpful music lessons on Ricci Adams's Music Theory Website, everything from FLASH movies teaching chords to a Keyboard Trainer.
If you are teaching a music class this term, the Music Theory Website is packed with mini-lessons that will give students the opportunity to practice their skills, even if they aren't in front of a piano.
Maybe your parents made you take piano lessons for ten years. Maybe you can give the Keyboard Trainer a whirl and see how much you remember!
Make momma proud!
