I think I have found something of a discrepancy (sp?) here. According to my whislte book from McCullough, D whistles are in concert pitch. All holes covered, first octave D is the space just below the staff in treble clef. Now, the book didn’t say anything about a difference between what the note sounds like on the whistle and how it’s notated, so I didn’t think there was one. I play that same D, at the same octave, one something else that I know is correct; namely, my pitch pipe. It seems to me that the whistle sounds an octave higher than written, and the music is transposed down an octave from actual pitch, like piccolo, I think. Technically, this is concert pitch by most people’s definition (a notation program on my computer, Finale 2002, thinks of it differently: to be concert pitch, it has to be notated at same octave it sounds, besides other transposing for other instruments that are like, Bb or something else, like trumpet. Actually, it is with this program that I first discovered the discrepancy).
In other words, does tinwhistle sound an octave higher than notated, or is it just me?
If it is, then I gues a low D wouldn’t actually start on d in the the middle of bass clef, but it would actually start on the d at the bottom of treble clef.
