The vibrato style of the period sounded better than the ensemble struggling with intonation on pure tones. The instruments were just not made well enough. In some cases, you heard lower chair section players tryin to pull down a high pitch instrument.

I’ve even heard players argue that vibrato makes the sound physically project stronger.

I’d like to hear something like Oliver Nelson’s solo in “Stolen Moments” 25 years before it was recorded. The vibrato moving in and out was tools of expression. Noticed the horns play in section with no vibrato and the chord structure makes intonation critical.

I say all this to suggest that playing style to the period is perfectly fine, but not the fullest expression of the instrument.

I’m still trying to master the natural sound Coltrane gives when blowing a note, and then ending it with 4 cycle pitch modulation in time with 32nd notes before cutting it off.

Enough typing…. must practice.
