Pianists, as well as many other instruments, often play with orchestral accompaniment, also known as a 'Concerto'. Check out this version of Denis Matsuev performing Dmitri Shostokovichs' Piano Concerto No.2, it's a delight to the ears!

Check out this version of "The Lark" recorded with a GoPro camera - you see what the pianist sees! Seems like all that scale practice paid off!

Just for fun, enjoy this parrot playing a splendid rendition of happy birthday. A true professional at work!
