I'm re-rearranging the score for a classical song onto guitar pro so it can be play on guitar, bass, etc.
I know that the guitar and bass are in the key of C, so instruments like the flute, baritones, trombones, and tuba are no problem tabbing out. Trumpet is easy to transpose since I've played it before and I know the concert notes for it.
But I'm having trouble with transposing the French horn, which is in the key of F. I need help with this. Anyone who has a better understanding of transposing than I do could really help me.
A note written as "C" for French Horn would come out as an F on concert instruments like guitar. (That's what being "in F" means - just as a trumpet "in Bb" makes a concert Bb sound when playing a written C.)
You may also need to bear in mind the octave question - esp if you are transposing a harmonised set of lines, and want them to come out in the right octave.
Here's a list of where the pitch of concert middle C (261 Hz) appears on notation for various instruments:
Piano (right hand), flute, violin, oboe: ledger line below stave
Guitar: 3rd space up
Trumpet in Bb, soprano sax, clarinet: D below bottom line
Tenor sax in Bb: D on 4th line up
Alto sax in Eb: A on 2nd space up
Baritone sax in Eb: A on ledger line above stave
French Horn: G on 2nd line up (the lowest 5 notes of French Horn are written in bass clef, btw).
Piano (left hand): ledger line above stave
Tuba is also in concert, but can't reach middle C
Bass guitar and double bass can just reach it, but (like guitar) are written an octave above concert, so middle C appears on top of the 4th ledger line up.
To look at it the other way, the note written as middle C (ledger line below treble clef, or above bass clef) for all these instruments will sound as the following concert pitches:
Piano, flute, oboe, violin, trombone: middle C (261 Hz)
Guitar, bass guitar, double bass: C, octave below middle C
Trumpet, soprano sax, clarinet: Bb below middle C
Tenor sax: Bb a 9th below middle C
Alto sax: Eb a minor 6th below middle C
Baritone sax: Eb a minor 13th below middle C
French Horn: F a 5th below middle C.
So, if you had a French Horn note written as a C below the stave (written middle C), you'd play it on guitar as an F on 4th string 3rd fret.
The French Horn has a similar range to guitar, btw. It extends a little lower (down to concert C below guitar's bottom E, written for the horn as a G on bass clef); and not quite as high - top note is concert F (guitar 13th fret top E), written for the horn as C 2 ledger lines above treble clef.
