+
+FAQ - LilyPond FAQs
+
+=head1 DESCRIPTION
+
+
+
+Q: I want to enter meterchanges inside the music.
+
+A: You can't; a meterchange is scorewide (well, staffwide in some
+modern music). If allowed inside the music, we get complicated and
+conflicting situations if two voices asked for (possibly different)
+meterchanges.
+
+You can mark certain spots, though: please check out F<cadenza.ly>
+
+
+Q: Why are [] around the notes, and () inbetween?
+
+A: [] designate beams, a note can only be in one beam at the same
+time. () is a slur, which connects notes. You need to be able to specify
+
+	a()a()a
