Normally accidentals are printed automatically, but you may also
print them manually. A reminder accidental
can be forced by adding an exclamation mark !
after the pitch. A cautionary accidental
(an accidental within parentheses) can be obtained by adding the
question mark `?
' after the pitch:
cis' cis' cis'! cis'?
The automatic production of accidentals can be tuned in many ways. For more information, refer to Accidentals.
