Piezo speaker melodies/chords?

Hello all,

I was just wondering if anyone has made melodies/songs using a piezo speaker and a BS2 (or a BS2 P24)... or even found chord frequencies?

I would love to see them!

Thanks! burger.gif

    Do you guys have a chart that shows what FREQOUT I should use for notes? Like A, B, C, D, E, F, G?

    http://www.borg.com/~jglatt/tutr/notefreq.htm

    found www.yahoo.com -> search: note frequency
    second result.

    The table reads per octave moving left to right.

    If you want pictorial: http://www.phys.unsw.edu.au/~jw/notes.html
    same search first result.

    Showing the way I found it isn't a crack, I search for a living, just sharing my methods.

    3 note chords cannot be done easily (if at all)·on the BS.
