As seen in the staff above, the typical Bach C trumpet suffers from a "zig-zag" intonation pattern. This necessitates false fingering and/or embouchure adjustment by the player. As a result, the timbre often changes from note to note.

Typical Bach C trumpet intonation pattern:

• G4 is flat

• E5 (and Eb) is flat

• G5 is sharp

Have a listen to Mike Thompson:

The intonation pattern after our recalibration is significantly improved. On the staff above, the width of each note in this staff is 10 musical cents.

When the notes overlap, you are assured that the intonation is at or below the level of the best human testers (plus or minus 5 musical cents).

All notes are in tune at or below the level of human discrimination.

Using Perturbation Theory as outlined by Bill Cardwell and working with our colleague Gary Bast, we physically tested many Bach C trumpets using a Salpingometer and found the inherent problems in their air column. We are able to manipulate the acoustic wave to improve the intonation down to the level of human discrimination.

No more false fingering the E, Eb, G or other notes. As a result you get an easier blow and more constant timbre.

This is a complicated process that really works!
