Quick Transposition Question Options

[Pixie*Porsche]

I'm writing a few pieces for 3x clarinets in Bb, 1x flute, 1x alto saxophone in Eb and a piano. Basically it's for a primary school.

If the clarinets are playing in C major and the piano is playing in Bb major, the saxophone is playing in G major, right? (IMG:style_emoticons/default/smile.gif)

Far easier and quicker.....

Bb instruments clarinets/trumpets etc deduct 2 flats from C instruments (piano/flute/violin etc key signature
Eb instruments deduct 3 flats
F instruments (horns) deduct 1 flat

So if C signature is Ab, (4 flats)
Clarinets are in Bb (2 flats)
Alto sax is in F (1 flat)

If C inst. signature has not enough flats, then add on sharps!!

So C sig Bb (2 flats)
Bb sig is C ( 0 flats)(2-2=0
Eb sig is G (deduct 2 flats and add on 1 sharp)2-2=0 +1

If you start with Bb instrument in C then
C instrument add 2 flats
Eb instrument deduct one flat (no flats in C key sig so add 1 sharp)

Just remember how many flats are in the key of the instrument you are arranging for and compensate for them....or better still buy a computer programme like Sibelius which will do it for you!!

You may find that quicker and easier. I find it completely confusing (IMG:style_emoticons/default/wacko.gif) (IMG:style_emoticons/default/huh.gif)

All you have to remember is that the note in the name of the instrument is the note that sounds when the player plays a notated C.

So:

Bb clarinet. Notation says C. The sound made is Bb
A Clarinet. Notation says C. The sound made is A

etc.

I find this much simpler (IMG:style_emoticons/default/biggrin.gif)

Yes, so then the arranger can write two or more scales in parallel to speed up the job of transposition. A little practice at writing out orchestral scores and it's soon second nature!

Good luck.
