In a \relative{ } passage, in order for Lilypond to work out the
absolute pitch of a note, it must have a record of the absolute pitch
of the previous note, even if there have been some intervening rests.
It seems probable that it has this information in all cases, whether
relative pitch notation is being used or not.How can I access the pitch value of this most recent note for use in a Scheme function after some rests? David
