Happy birthday, Mozart!
Yes, you heard me right. Today is Mozart’s birthday. He recognized the importance of studying fugues and, supposedly, according to a student, a volume of Bach’s The Well-Tempered Clavier was always lying open on Mozart's pianoforte.
Mozart arranged several of Bach’s fugues for strings. It is not known whether Mozart did this to further his abilities in writing counterpoint, to pay homage to J.S. Bach or just to have fun!
Although we’ll never know all the answers, we can all, luckily, enjoy the fruits of Mozart’s (and Bach’s) labors. Have a listen to several examples here.
