Hi David, I would hypothesize about your data as follows: When you blow hard while playing a low note (long and wide reed), the pressure on the upstream side of the reed is greater than the pressure on the downstream side of the reed. This higher-than-normal upstream pressure pushes against the large flat reed face as it rebounds in its vibration cycle, slightly dampening the reed’s movement and slowing it down. Hence, the reed produces a slightly lower frequency (note). When you blow hard while playing a high note (short and narrow reed), the upstream pressure has little dampening effect on the reed because of the reduced surface area and increased stiffness of the small reed. Does anyone see a problem with this hypothesis? Lowboy

Thanks Lowboy, that's a great hypothesis that I now feel compelled to test!!! Stay TUNED!
Please, do you have a tuning chart where I can see the exact frequency of each note? A tuning which I’m able to play chords as well. Thank you!
Good!
