This PianoTweet is a mixture of major and minor chords.
Usually a major chord stands for
joy, a light mood, fun, happiness…
A minor chord is generally associated with
a more melancholic mood, sadness, darkness,
So, a mix of these type of chords might illustrate
a mixture of moods.
Similar to a memory.
For most human minds it seems easier to remember
the better part of memories.
That’s not quite true, in my opinion.
There are types of memories that are balanced,
between major and minor moods.
So is this PianoTweet,
sounding both joyful and melancholic.
