Place dynamic marking under bar line (move dynamics horizontally)

Question

I want to create a crescendo that extends over two measures.

The following code

\relative c'
{
    c4\pp\< c4 c4 c4 | c1\ff
}

compiles to

which is almost what I want. However, I would like the ff markings to appear further to the right, directly under the very next bar line, to indicate that the last whole tone should have a gradual increase in volume as well.

How can I achieve this?

Answer 1

You could use spacer rests to "move" the fortissimo to the end of the second bar:

\relative c'
{
    c4\pp\< c4 c4 c4 |
    << c1 { s2. s4\ff } >>
}

This results in:
