I have always admired Johann Christian Bach's music, as it has a wonderfully lyrical quality, and he had a great gift for writing beautiful melodies.
I transcribed and edited this tune [originally a sonata for more than one instrument in reality] and found it very suitable to play. It has a characteristic lilting rhythm [ a sort of galloping gently along character]. Starting in A major, before then changing to C major, and then back again at the close.
