Ah, interesting, thanks! It’s basically a Boehm-keyed csakan with a ligature thingy for swappable blocks or windways, and a lip lever for dynamics. Yes, $2K is dear.
The BIG difference is there is no reed or reed embochure to mess with, just learning the fingering and once that is learned you can cross over to a reed instrument pretty easily (sax fingering).
Well I still don’t know what key whistle to use/purchase. Perhaps I should seek out the cheapest whistles I can find, purchase one of each and just play along in whichever sounds right for which ever tune she plays and then upgrade as and when necessary. I wonder if you can get a deal on a job lot?
There you are - what is the cheapest set of whistles you can find?
Here is my list that I use as a quick reference when I play my Bb trumpet with other “C” instruments. So from the top of the list, if the piece you are going to play is in G# (Ab) for your cornet player, you will need to play with a F# whistle. So as discussed, the piece in C will be played with a Bb whistle, or the Piece in E will be a D whistle etc. Clearly more than 25 words and adding a little mud too…hope it all lines up.
Instrument Pitched In:
Piano (Concert Pitch) = Bb Trumpet
F# = G# (Ab)
B = C# (Db)
E = F#
A = B
D = E
G = A
C = D
F = G
Bb = C
Eb = F
Ab = Bb
Db = Eb
Gb = Ab
Well not necessarily because you can use a D whistle for G, a Bb whistle for Eb etc. with different fingerings, but that is a whole new topic which you can find loads of info on with a quick search.
For fingerings on whistles, the definitive site is: http://www.fullbodyburn.com/ and covers this topic very comprehensively - worth wading through the masses of info to get an understanding of what is possible.
Only if you want/need to play in every key imaginable. You can play lots, maybe most, Irish music with a D whistle. A couple more whistles (I’ll leave it to the experienced players to advise which ones) will cover just about everything else in ITM.
Edited to add: Oops, just read the original post again. You might need more whistles for non-ITM depending on what tunes you are playing. You probably won’t need every key available. Look at what you will be playing and get whistles to cover those keys.
