Cut Time (2/2): Alla Breve Explained

Short answer

Cut time is the 2/2 time signature, also called alla breve: two half-note beats per bar. It is written as a C with a vertical line through it. The bar holds the same four quarter notes as 4/4 but is felt in 2. A tempo of half note = 60 equals 120 quarter-note BPM, and each bar then lasts 2,000 ms.

What does cut time mean?

Cut time means the half note gets the beat and each bar holds two of them. The top 2 counts two beats; the bottom 2 names the half note as the beat unit. The symbol, a C “cut” by a vertical stroke, gives the meter its English name.

The Italian name alla breve means “at the breve”. In older notation the breve was the main counting unit; today the term simply signals a two-beat bar with a half-note pulse. Cut time is a simple duple meter, like 2/4 time, but with beats twice as long on paper.

How to count cut time in 2

Count “1 & 2 &” across the bar, with each number on a half note and each “&” on a quarter note. Players who first learned 4/4 often count “1 2 3 4” at first; the goal of cut time is to feel only the two big beats.

A conductor beats cut time with two strokes per bar, down and up.

Converting a half-note tempo to quarter-note BPM

Double the half-note tempo to get quarter-note BPM. A half note lasts two quarter notes, so half note = 60 means quarter note = 120. Our calculators and metronome count quarter notes, so enter 120.

quarter-note BPM = half-note BPM × 2

The reverse also holds: a 4/4 chart marked 200 BPM is often easier to read in cut time at half note = 100. For quick doubling and halving, the tool for halving and doubling tempos does the arithmetic.

Cut time vs 4/4: same bar, different pulse

A 2/2 bar and a 4/4 bar contain exactly the same notes and last the same time at the same quarter-note BPM. The difference is the felt beat: two half notes instead of four quarter notes.

Composers choose cut time when the music moves fast enough that four beats per bar would feel busy. A march at 120 quarter-note BPM felt in 2 has a beat every 1,000 ms, a comfortable walking pulse; counted in 4 it would click every 500 ms. The 4/4 time guide covers the four-beat version of the same bar.

Where cut time appears

Cut time is the common meter of marches, fast show tunes and quick Classical and Baroque movements. John Philip Sousa’s “The Stars and Stripes Forever” (1896) is a well-known march in cut time. Fast show tunes and musical-theater overtures are also frequently written in 2/2.

Baroque and Classical composers used the alla breve marking for quick movements whose notes would look crowded if beamed in four. Among all the time signatures and their symbols, only 4/4 and 2/2 have letter-style signs.

How to practice cut time with a metronome

Make the metronome click on the half notes, not the quarter notes. Hearing only two clicks per bar trains the two-beat feel.

  1. Convert the marked half-note tempo to quarter-note BPM: half note = 60 becomes 120.
  2. Enter 120 BPM, 2 beats per bar and a half-note beat unit; one click sounds every 1,000 ms.
  3. Count “1 & 2 &” and play quarter notes on each syllable.
  4. Switch clicks per beat to Eighths to hear the quarter notes when the passage gets busy.

The half-note beat unit is available on the online click metronome.

Questions

Is cut time the same as 2/2?

Yes. Cut time, alla breve and 2/2 are three names for one meter.

Is cut time faster than 4/4?

Not by itself. At the same quarter-note BPM the notes are identical; cut time only changes the felt beat. In practice it is chosen for faster music.
