Saxyann, Cool horn, but those Mark VI's are very inconsistant. I owned one that was ok and I owned one that S8cked. The MarkVI is all about the ego. About four years ago, I purchased two new horns. and...... They say you can't be in love with two women at the same time!

Mark VI's are indeed a different story for intonation versus a lot of other horns. I play a Mark VI alto as my main horn, and the intonation is indeed a little bit out there. What I recommend doing is sit down with a tuner, and figure out how far out the pitches are. For sharp notes, try covering different keys. The tone might be a little different, but if you're shooting for better intonation alternate fingerings are the next step. I use my horn for classical as well as jazz, and classical can be quite the bout when trying to get everything even and in tune... especially some of them altissimo notes. It's all about experimentation though. The horn's fine, you just need to learn to grow with it.

This is a common situation occurring when the volume and or resonant frequency of the mouthpiece do not match the instrument correctly. A mouthpiece with a little smaller chamber will balance the intonation between the high and low registers better. I like a Bari Richie Cole 5. Or, if you really like the way the Meyer plays, other than the intonation, I can tell you how to make an insert for the throat of the mouthpiece which will fix your problem.
