Or use Richard's lower case idea [v:1+].


Hmmm...

Why not allow both for transient voices *both* on separte lines and as through inline fields? That seems to be more or less consistent with how other inline fields work in ABC.

The problem with the & notation already existing still remains, though...

I'm thinking aloud here, but, how about this:

--------------------------------------------------------
Transient voices

A transient voice is a temporary voice linked to a main voice for shorter or longer sequences. In theory it is possible to have a transient voice running through an entire piece, but that is not recommended.

A transient voice is named with a v: (lower case v!) field. It's name is the same as its parent voice with a + added.

The v: field can be used both inline and on a separate line.

To start a transient voice in the middle of a bar, the x spacer can be used.

To start a transient voice at a bar in the middle of a line, one can either use an inline v: field or "empty" bars similar to what's used on w: fields.

For backwards compatibility, the sign & is allowed as an equivalent to an inline v: field. This is, however not recommended since it may conflict with future extensions of the ABC standard.

Examples:

X:1
T:Ex. 1
N:The transient voice starts at the beginning of bar two.
M:C
L:1/4
K:C
V:1
CDEF|GABc [v:1+]G2FE|]

X:2
T:Ex. 2
N:The transient voice starts on the second beat of bar two.
M:C
L:1/4
K:C
V:1
CDEF|GABc [v:1+]xGFE|]

X:3
T:Ex. 3
N:The transient voice starts at the beginning of the line.
M:C
L:1/4
K:C
V:1

v:1+

N:The transient voice starts at the beginning of bar two.

CDEF|GABc|]
v:1+
    |G2FE|

X:5
T:Ex. 5
N:Same as Ex. 1, but with & as a substitution for [v:1+]
M:C
L:1/4
K:C
V:1
