Guide to Flügelhorn Tapers

The following information is reprinted with permission from www.mouthpieceexpress.com.

Confused about tapers? Don’t feel bad—you’re not alone. Here’s the scoop on flügelhorn mouthpiece tapers. Just remember, if you are using the wrong taper, you may be experiencing poor intonation and response!

LARGE Morse taper

Commonly known as Standard Taper, the LARGE Morse taper is used by Yamaha, Getzen, Callet, Benge/King/Conn, Holton and older Kanstul 1525 flügelhorns.

Note: Only a very limited number of early Model 1525 Signature flügelhorns were built with mouthpipes to accept the large Morse (Yamaha) taper. If you own a Model 1525, more than likely it has a receiver that accepts the small Morse (Bach) taper. The mouthpipe is marked with a letter “B”.
SMALL Morse taper

The so-called “Bach Taper.” Bach, Courtois, newer Couesnon, Kanstul 1525 and some European flügelhorns use the SMALL Morse taper.
FRENCH (straight) taper

Also known as Couesnon Taper, French taper is used by original Couesnons, Flip Oakes “Wild Thing,” Kanstul CCF 925, and original F. Besson flügelhorns.
