Hi all,
To clarify the problem (or to do just the opposite), here is a testfile
with a number of possibilities.
The file is made for 3 music lines in order to see a behaviour when an
automatic new line occurs.
This are my taughts on this
Bar 1 - multiple meters
this is an example of 'variable meters'. Another notation practice is
'alternating meters' denoting a pattern of meter changes, eg. '4/4 + 3/4'
bar 1 beat 2 and 3 signature change is this common?
according to Gardner Read, Music Notation, modern practice is to omit
'cancelling signatures' (naturals) at key changes. There are a few
exceptions to that rule, most important when changing from a key with
signatures to a key with no signatures (c major and a minor). The
general rule (according to G. Read) is to precede key changes with
double (bar) lines. I've seen key changes without double lines, though.
bar 1 beat 4 the 'f' in the lower staff shows how confusing this is
bar 2: i vote OK
there should be no cancelling key
bar 3: autoamatic new line this i vote OK, but not the different
signatures in the instruments
what is the problem? Different keys will inevitably occur in scores with
'transposing instruments', eg. clarinets and French horns
bar 4: OK
bar 5: better
not IMHO, there is no reason for omitting double bar lines and the
cancelling keys are unnecessary
bar 6: rather not? or is it forbidden? Select one ot the 3 lines in the
source to see other behaviour.
the key changes should be after the double line
bar 7: OK except on beat 3 (keychange on only 1 instrument, signature
change without bar line)
bar 8 and 9 : both OK or is there a preference?
in case of clef change at the start of a new bar the clef should be
placed before the bar line
bar 10: a meter without fraction
belongs to modern notational practice. Furthermore you'll often find
fractionless meter '3' in modern edtions of early music at triple meters.
bar 11: Ok except the bass clef schould be repeated, is this possible?
bar 12: probably not.
there is no real key change. Therefore the key signatures should be omitted.
