Wolfram Alpha doesn't know. (What good is it, in that case?)
So I had to turn to Yahoo for the answer.
well at a rate a 105 words per minute and a tempo of 150, you should finish the song in a aproximitaly 38 minutes and 34 seconds
For simplicity of computation, let's round it to 45 minutes to account for tiredness.
So, in a three hour period, you could sing the song four times.
And in a twenty-one hour period, you could sing the song twenty-eight times.
Of course, I have assumed sobriety in these calculations. If the singers were actually imbibing while singing, the rate of song completion would decline dramatically over time.
Now you may be wondering why I am wondering how many times one could sing "100 Bottles of Beer on the Wall" in a twenty-one hour period.
For the answer, stay tuned for a future post in the Empoprise-MU music blog. The post is scheduled to appear on Monday morning - well, Monday morning in the western United States. If you're somewhere else, it may appear on Monday afternoon, Monday evening, or perhaps even on Tuesday.
P.S. The title of the post really has nothing to do with music. I took it from here.
