So much wrong with this...  First, (+6 2) calls 6 as function on 2.
That doesn't work.  You need (+ 6 2) here.

Then Scheme expressions written using # in the middle of music are
expected to be music expressions.  If you want to insert an actual
duration, you need to write it preceded with $ so that it can have
different type (and trigger different syntactic rules).

But $8 is not a duration.  $(ly:make-duration 3 0) would be a duration.
