And they recently linked to an iPad app that looks interesting.

I gave up TV some years back as a mental health move and to free up time. If this catches on, though, I might go out and buy one. Via that invaluable internet resource and productivity enhancer, Mr. Dave Barry.

Harmonic Tuning

This afternoon it was Dick (trumpet), Gabby (baritone), Bill (Eb tuba), Judy on percussion and singing, and me on horn and flute. Trying to develop a free form tuning etude to help people hear intervals other than unisions and octaves, while gaining an appreciation of the harmonic series and how it establishes the range from pure consonance to very dissonant.

First had Bill play his middle Bb and Gabby the F a fifth above, shifting down to the Eb and back. Once that was established I played the Bb below middle C and Dick played the third and fifth and flat seventh. What really worked was Bill and Gabby playing those Perfect Fifths and Perfect Fourths, because they could really hear the coherence when they were right. My guess is they never really realized fourths and fifths are more consonant than thirds.

So the place to start with the etude is with the fifths and fourths, because I think they're easier to hear and recognize as being in tune than unisons and octaves. There's almost a sense of feeling the standing waves in the air, that octaves don't generate, at least to me. Another way of putting it is that the fourths and fifths suggest triangulation when focussed, whereas octaves are more like lining up points in a straight line.
