Hi I hope somebody can clarify something that has bugged me for over 50 years. I saw Count Basie in Birmingham (the real one not Alabama) around 1961. A Sax player took a solo and as he went up a register there was what I can only describe as a loud squeak which I thought sounded awful. However I was totally blown away by the professionalism of the band/orchestra because from then on as he flew through the notes at that precise moment there was a similar pitch blast from the trumpet section.
What was going on?
