Melodyhound should delight the mathematicians among you, especially its use of the "Parsons Code," or "melodic contour," which is able to identify melodies quite accurately just by knowing the sequence of rising or falling pitches: http://www.melodyhound.com/melodic_contour.0.html
You can also enter notes from a piano keyboard, sing, whistle, or tap a rhythm on your computer keyboard. It will try to find a match, with surprisingly good results. My intuition says there's some information theory at work here... db ----- Original Message ----- From: "Rob Howard" <[EMAIL PROTECTED]> To: "'The Friday Morning Applied Complexity Coffee Group'" <friam@redfish.com> Sent: Tuesday, December 26, 2006 10:38 PM Subject: Re: [FRIAM] Mathematical Search and Regular Expressions > Math ability and music ability are related.
