Do I have this right?
If I have a whistle in the key of D, it also plays the key of G if cross fingered. That much I have.
Tell me, if I were to get a G whistle, would it also play the key of D if cross fingered?
One more…
If I have sheet music written in D and an A whistle and I play the whistle using the same fingering as if it were a D whistle, am I playing in the key of A?
Thanks. Hope that all makes sense to someone.

You can play in the key of D on a G whistle, but you would have to fix the 7th scale tone instead of the 4th. It would be like playing in the key of A on a D whistle - the 5th scale tone being the starting note.
Yes.
Hope that helps…
Hi Mike
Have a good look around this site for transposing scales…
http://hyperphysics.phy-astr.gsu.edu/hbase/music/tempercn.html
If you can’t find what you are looking for there, I will post the scales and frequencies you ask for and some suggested “harmony” key scales. The Scales of d’ major and b’ minor,for instance,have the same sharps in their scales but are only a minor 3rd apart. Minor scales are good “harmony” choices for ensembles.

Limuhead, that did help.
Thomas, I don’t speak music I’m afraid, so whatever you just said is Greek to me.
Let me ask this…
If I have a low G whistle and played it like I would a D whistle playing the key of G, you know, cross fingering, what key is that?
Now do you understand my confusion?
Thanks for your time.
hmmm, it is capable of several keys cross-fingered
The key of C.
You would be playing in the key of c - if the scale you are asking about starts with the note played with the three top holes covered and the three lower holes open.
Check out the Chiff and Fipple Deciphers Whislte Keys page (http://www.chiffandfipple.com/whistlekeys.html)
I hope I haven’d added to the confusion

Answer is : C (perfect 4th up)
To play the key of D starting xxx ooo, you’d need an A whistle.
The Low Whistle Book has the best chart I’ve seen that helped me understand these questions. I put it on a chart on my computer. Would I get into some copyright violation if I pasted it here?
In the book they talk about six finger, three finger, two finger starts ect (all six fingers down - D on a D whistle, three fingers down - G on a D whistle, two fingers down - A on a D whistle and so forth for different whistles/keys)
it helped to see this chart

Thank you to those who kindly relpied.

This music stuff…go figure!

Another way I look at it is this…
The key of D has 2 sharps in the key signature, so a D whistle has 2 sharps “built into the whistle”. If you flatten the ‘all open holes note’ (C on a D whistle) through crossfingering you’re taking out a sharp, so that leaves one sharp in the key signature, or G.
Do the same on a G whistle which only has one sharp built into it, you’re down to no sharps, or the key of C.
Do the same on a C whistle, which has no sharps, and you’ve got one flat (B) which is, er some other key I forgot the name of right now.
The A whistle has 3 sharps built into it, so doing the cross finger thing brings you down to 2, or D. etc.
And now I’ve thoroughly confused the issue, back to the music…
Music really is very mathematical, isn’t it?
Now that I understood!
