Transposition

How to transpose a melody in four steps, the same tune shown in three keys, a transposing instruments table, and a worked Bb trumpet example.

What's inside

• Four steps for transposing a melody: find the interval, write the new key signature first, move every note the same number of letter names, and copy every accidental's effect
• The same tune written out in three keys side by side, showing the pattern stays identical
• A transposing instruments table — written versus sounding pitch and the key signature adjustment for each
• A worked example transposing a Bb trumpet part, from the sound wanted through to what the player reads
