"Wachet auf, ruft uns die Stimme" is one of six Schübler chorales by Bach. It is also known as "Sleepers, Awake!".
Ton Koopman's recording was a source of inspiration for me, a fact that is evident in my tempo and ornamentation. It is often performed at a slower tempo, which I enjoy very much. However, the faster tempo gives the piece a cheerful, bright sound that I just couldn't resist.
