Find the Best Key for Your Voice
Enter the song's lowest and highest notes and your comfortable range — it calculates how many semitones to move, the new key and the capo position for guitar. You can measure your range with the mic.
1. Find a key for your range
2. Male key ↔ female key, quickly
These are the usual 3–5 semitone options. Every song's range is different, so the calculation in step 1 is more accurate.
FAQ
How many semitones should a woman raise a song sung by a man?
It depends on the song and the voice, but usually 3–5 semitones up — or the same key an octave higher. The most accurate way is to compare the song's highest and lowest notes with your range, which is exactly what the calculator above does.
And a man singing a woman's song?
Usually 3–5 semitones down, or the original key an octave lower. If the original key drops comfortably an octave, you don't need to change it.
How do I know a song's highest and lowest notes?
If you have the sheet music, look for the highest and lowest notes in the melody.
Is my voice recorded when I measure with the mic?
