Move a musical key up or down by any number of semitones and read the new key at once. Pick your starting note, enter how many half steps to shift, positive for higher or negative for lower, and this tool wraps around the twelve pitch classes to land on the correct new key. Transposing is what you do when a song sits too high for a singer, when you switch instruments like moving to a B flat trumpet, or when you use a capo on a guitar. Because equal temperament divides the octave into twelve equal steps, transposing is just counting: shift every note by the same amount and the relationships inside the key stay the same. The tool shows both a sharp spelling and a flat spelling of the result so you can pick the one that reads best for your chart.
You enter a starting key and a number of semitones, and it returns the new key shifted up or down by that amount.
Yes, use a negative number of semitones to move the key lower and a positive number to move it higher.
Moving up two semitones raises a key by a whole tone, and moving up twelve returns to the same key one octave higher.
