Because the clarinet only has odd harmonics in its spectrum, octaves in multiphonics are impossible. But there are a few that come very close, in a way that I find interesting and rather beautiful. These aren’t perfect octaves by any means. But the ways in which they come close produce some totally unique multiphonic sounds. They are close, beating multiphonics that vibrate in the mouth of the player and sounds almost sung.
They aren’t easy to play, but they aren’t as difficult either (I think). There are definitely dyad multiphonics that are far trickier.
The notes inside () represent pitches that you cannot separate in the multiphonic. Pitches are, as ever, transposed.
|30||This one is quite complex, and the top note bends really easily, so it needs to be controlled for the octave effect|
|67||You can either have the F# or the C quarter sharp here (I demonstrate the F# second in the recording)|
|142||The octave is buried inside this complex multiphonic…|
|177||Getting rather far from our octaves with this one, but I find it so beautiful… a little tricky to keep both pitches even, as you can hear.|
|241||Again you can either have the D or the G quarter flat here – I demonstrate both|
|265||Once again the octave is buried within the multiphonic|
|330||And last but not least — actually this one may well be my favourite.|
