I recorded four mystery demos that are in my keyboard's repertoire. (weird as it may seem my keyboard actually has a mind of its own....and so does my recorder
Anywho, I lost the manual and in the manual were the names of the pieces and their composers. My keyboard has 8 demos in total: 3 being of Chopin (Etude 10/1, Waltz 18/1, and a Nocturne) and one of Schumann (Kinderscenen: About Strange Lands and People).
So if you could spare a few minuets and listen to the four attached mystery pieces and see if you can identify them. Thanks.
p.s. It might be very quiet or it might be normal volume...who knows..my recorder and keyboard are plotting against me
