I purchased a banjo a couple of weeks ago. After two weeks of testing, I am fairly certain that one may not play a banjo and be sad at the same time. If a sad person tries to play the banjo, either they will become happy in very short order, or they will promptly put the banjo down, being unable to play it. Banjos will not abide sad players.
I suspect there is a similar issue at work when we praise God, but I’m still investigating that one.
