Often times I hear this question. You might get the impression from my last post that all Chazzanut songs are slow and serious, and this is a popular misconception. There are many really exciting and fast Chazzanus pieces, and chief among them are the songs of Moishe Oysher.
This one starts slow but it's a fast song:
He was able to sing playfully, sometimes even carelessly (i.e. In his sheibone, which is sang in short in almost every Chabad shul) and he was able to give each of his songs a character and feel of its own. For him, being a chazzan was very much alike being an actor - interpreting every moment in the right way and impersonating his songs. He aspired to be as popular as Yossele Rosenblatt, who was known in non-Jewish music circles as well, however Moishe Oysher never took off in the music and video industry at the time. However his Chazzanut style was truly unique and a much more upbeat than what the world had seen until then, and until today his songs are studied and performed in many Chazzanut concerts.
