The # simply indicates that what follows is not a high-level LilyPond
expression, but rather a (low-level) Scheme expression. In particular:
#"piccolo" ... a Scheme string
#UP ... the value of the Scheme variable UP (the value is +1)
#'blah ... Scheme symbol blah (e.g. the variable rather than its value)
#'(0 . 0) ... A scheme pair of numbers
#(ly:something args) ... the Scheme function ly:something applied to the args
Cheers,
Reinhold
