Trumpet Sounds - Alto Saxophone
The usable range of the trumpet sounds technique on the alto saxophone is between the low B♭ and the high C two octaves higher. Beyond this point, the technique becomes too strenuous on the lips to produce stable pitches.
A graph of the hertz output has been added below. When plotted, the curve that is produced is representative of an exponential curve with an R squared value very close to 1. This means that the representative model is accurate and within an acceptable range.
