The Hamlet Project

What is the meaning of trumpets?
What do drums signify?
Harpsichord means Harpsichord
Ukulele, Ukulele
But those two bass notes mean a shark is coming.
Those three young voices singing in ascendance
Mean magical help is on its way.
When we hear those sharp strings striking
In quick succession,
We know it means a knife is doing quick work.
Music in the middle of the night in Denmark
Means that the king is up drinking, apparently.
