A jazzy improvisation over a simple chord progression.
Sometimes it is good to be alone. In music just the same. You can lead the melody and follow it at the same time, developing it much further. It does not matter where the melody takes you – there is no need to be afraid of uncharted grounds. You can make all the mistakes you want, change the rhythm , change tonality. You can pause and wait a couple seconds, catch your breath and then move on.
