Fermata, breath mark and the rest across several measures
Five signs to hear and see. Four of them change nothing in the sound — they speak to the player. Only one really counts measures.
Some signs change no pitch at all and still decide how a piece sounds. The fermata holds; the breath mark makes room for air; the caesura cuts off. How long, is written nowhere: the player decides.
That is exactly what is measured on this page. Every sign stands twice side by side — left without, right with. In four of the five, pitches, entries and durations are identical in both pictures; only the engraved image changes. Press play here and you will hear no difference, and that is not a fault of the page but the thing itself.
The fifth sign is different. The multi-measure rest gathers several empty measures into one picture and writes the number above it. In the sound the full silence is there — so it really does count.
Fermata
Above the last note of the first measure stands an arc with a dot. It says: hold this note longer than it is written. How much longer is written nowhere. Nothing changes in the sound data — entries and durations are the same on the left and on the right, measured. The sign addresses the human being, not the machine.
Fermata over a rest
The same sign over a rest stretches the silence instead of a note. It often stands just before a new section: the listener is meant to hear the break. Here too the sound stays unchanged; the rest lasts the same in both pictures, and what goes beyond that the player does.
Breath mark
A comma above the staff means: take a breath here. Wind players and singers need it, string players re-set the bow. The time for it is taken from the note before — the measure stays full, the note is simply released a little earlier. None of this appears in the sound.
Caesura
Two short slashes above the staff, called railroad tracks in the orchestra. They cut more sharply than the breath mark: everything stops, and afterwards something new begins. How long the silence lasts is again for the player or the conductor to decide. The sound stays the same in both pictures.
Rest across several measures
Here something does change. On the left the empty measures stand one by one; on the right they are gathered into a single picture: a thick bar with the number of measures above it. In the sound the silence is equally long in both cases — so it really is counted. In orchestral parts this saves whole pages, but it demands steady counting.
What stands in the picture and what stands in the sound
The fermata over the last note of a section is the most common of these signs. Roughly one and a half to twice the written value is usual, but that is a habit, not a rule — in a choir the conductor gives the cue to move on; alone, the breath decides.
Over a rest the fermata does the same thing: it stretches the silence. The breath mark, by contrast, takes its time from the note before it rather than adding any — the measure stays full. The caesura, two short slashes above the staff, cuts more sharply and often stands before a new thought.
In orchestral parts the multi-measure rest saves whole pages. Instead of twenty empty measures there is one thick bar with the number above it — the counting still has to happen, and whoever miscounts comes in at the wrong place.
