In viral times, here’s music for washing your hands

Coronavirus advice from the Boston Camerata, now going viral on their site:

HOW TO WASH UP IN MUSIC
We are advised, on good authority, that frequent washing of the hands is an excellent precaution against the day’s virus, and that singing “Happy Birthday” twice (circa 20 seconds) while doing so will help you time the process correctly.

Lest you be deterred, however, by the thought of having to perform that sappy tune twice in a row, Boston Camerata Labs (TM) suggest a few other washtime melodies that might time out acceptably, while giving somewhat more musical pleasure to the process. Our lab-tested examples hereby follow, in music-historical chronological order.

Moniot d’Arras (13th century): Ce fu en mai, 21 seconds
J. Dowland (1563-1626): Come again, sweet love (only once through the second phrase) 25 seconds
Franz Schubert (1797 -1828): Das Wandern ist der Müller’s Lust (one strophe), first song from the “Schöne Müllerin”: 22 seconds
Anon. 19th century: O My Darling Clementine (twice through) 20 seconds
W.C. Handy (1873-1958): Saint Louis Blues, just the minor key phrase with the diamond ring bit: 20 seconds

Enjoy your melodies! “Keep it clean!” — Eleanor of Aquitaine, to her troubadour Bernard:
