Every day I learn something new. (Did you notice how I made this all about me in the very first sentence?) According to Webster’s Dictionary, Adagio means “at a slow tempo —used chiefly as a direction in music.”
Today’s song is number 59 on the big countdown of 100 Classical Masterpieces, and is entitled Adagio in G Minor. It is credited to Tomaso Albinoni (1671-1751), but it is thought to have been written by Remo Giazotto, a 20th century musicologist and composer, who was a cataloger of the works of Albinoni. My version is a bit faster than the original, so not very adagio at all, really.

And here is Number 60 – Piano Concerto No. 5 in E-Flat Major by Ludwig Van Beethoven (1770-1827).
It’s Beethoven’s Fifth Concerto.
