I have a tune that’s in Ab minor that I’d want to play along with, but on whistle I’m not sure how to do this, which whistle to use.
Without having an Ab minor whistle (if such a thing exists!), I don’t know what would be best to use.
I’m a bit confused and would appreciate help.
Unless you want to play with a recording, I’d change it to A min; to play in Ab minor, you’d either need to be REALLY good at half-holing, or have a B (or F#) major whistle hanging around. If you are pretty good at half-holing, then it could be done on a Bb whistle - play a minor scale starting on C# fingering (as if a D whistle), so:
C#, Eb, E, F#, G#, A, B (or Bb, depending on the exact scale), C#.
Or you could use an Eb whistle: G, A, Bb, C nat, D, Eb, F# (or F nat), G.
Or an F whistle: F#, G#, A, B, C#, D, E (or Eb), F#.
Personally, I think Bb would probably be easiest, purely because it’s easier to half-hole on larger holes. You may not agree 
…
It might just be easier to ignore the above and play in A min.
If you’re playing with other musicians, try to convince them that Ab minor is an evil key. Truly evil. And get them to change to A min.
Good luck!

It’s an a capella recording I’m trying to accompany…so I can’t change the key (or it would be in D!). It’s kind of slow, though so I may try half holing on my Gen Bb..
I have a lot in B major too that I tend to play along with on an E when I can.. E would not work for Abm though. I’ve tried it on this song and it just…isn’t right.
