Parallel Keys
Same starting note, different scale. Pick a tonic below and hear exactly which three notes change when you switch from major to minor.
Parallel vs. relative: don't mix them up
Relative keys (like C major and A minor) share the exact same notes but start in different places. Parallel keys are the opposite: they share the same tonic (starting note) but use different notes — C major and C minor both start on C, but sound completely different.
