Sax Workshop Sept 07

Loved it! This piece really goes places. It looks like there was more to it by the 1/4 time change at the end. However, it stands alone as is. If there is more, though, I'd like to hear it.

My first question is regarding vibrato: There seems to be a natural increase in the vibrato the longer a note is held. I can guess that this has to do with breath more than style. However, I'm sure it can be executed "sans vibrato".
On the last three measures all of the played tones are of equal value. Yet, the third note seems to get more vibrato each time. Again, is that to do with how you breath? or is it stylistic?

I too would like to know if there is more of this piece. I really liked the use of the glissando and the bending ideas are very effective. Is this a true solo piece or is there an accompaniment?
