[Smooth Sop Berator]

I just listened to Charlie Parker's solo on Passport, and he's on the edge of a chirp for much of it. I think it contributes to the effectiveness of the performance, and have noticed this on many other recordings, so I'm wondering if it is intentional, much like a vocalist whose voice cracks to add soulfulness to a song, or just happens and becomes a free bonus. Anyone care to add some insight to the subject?

I don't think anyone chirps intentionally.

 

[mike713]

yeah it definitely isn't intentional... i also think it contributes negatively to the effectiveness of the performance in the case of Passport

I don't think anyone chirps intentionally.

Birds.
