Transposing moves every note by the same interval. Do each note in two steps: count the letter names for the number, then fix the accidental for the semitones.

Two steps for every note

A major 3rd is 4 semitones: F sharp

To transpose is to move music up or down by one interval, keeping its shape.

  1. Count the letter names: up a 3rd from D is F.
  2. Fix the accidental: a major 3rd is 4 semitones, so F sharp.
