hears a clue.....play a D, listen to it. then play a up a fret to an Eb, what is the difference? One's higher and one's lower right? Yeah that is right, but what else is different?

Here it is...

The D sorta of has a "dah, dah, dah" sound and the Eb has more of a "nah, nah, nah". The D is alittle brighter than the Eb, which is softer and more sedated. But the Eb is higher than the D right? See each tone has its own characteristic is the way. It's not highness of lowness, its just a feeling of the note.

Listen to the F#...."wier, weir, weir". it has a buzz in it, huh? Like a fly buzzing in your ear.

Make sure your in tune to.
