How can you tell if a key has changed in a song?
In general there are a couple of beats where chords are shared between the two keys. You can think of these chords as belonging to both keys and establishing the transition. Once you hit a new chord or tone that does not belong to the first key, at this point you are definitely in the new key.
How do you find the tonic of a song?
We can find the tonic at the beginning of the melody, but also at the end of it. A common practice is to extract the scale of the melody. When no other pitch seems to stand out with the stability of the tonic, take the last note and arrange the other notes after it in ascending order. The first step is the tonic.
How do you change the key of a song?
The way to change keys with the chromatic scale is to walk up (or down) until you reach the root note of the new key. So if you want to change the key from G major to B major, you can use this walkup: G – G♯ – A – A♯ – B.
