Solution to Exercise 6.1:
Solution to Exercise 6.2:
Play the part you have transposed; your own ears will tell you where you have made mistakes.
Solution to Exercise 6.3:
Transposing up a major third (Major and Minor Intervals), to E minor, puts the song in a better range for a soprano, with a key signature that is easy for guitars.
Solution to Exercise 6.4:
The trombone part is in C in bass clef; the horn players are used to reading parts in F in treble clef. Transpose the notes up a perfect fifth and write the new part in treble clef.
Solution to Exercise 6.5:
Put the capo on the first fret to raise the sound by one half step. Then transpose the chords down one half step. You will be playing in G, a nice strong key for guitar, but sounding in A flat. For more on transposing chords, see the final section below.
Solution to Exercise 6.6:
The best solution here is probably to put the song in the key of G. This is three keys lower, and has easy chords.
