How to Notate Musical Rhythm

Notating rhythm often is the most difficult part of music notation. In this music theory lesson, I will show you principles that will help you to notate rhythm in the clearest possible manner. When I teach this lesson in the classroom, I’m often asked, “Why do I have to do it this way?” I always say that you can notate your music any way you want. But your goal is to communicate the music, and obviously you want to do it in the clearest possible manner.

The secret behind notating rhythm clearly is to clarify the beat, that is, make the beat easy to see on the written score. Following are principles using the most common time signatures. These principles apply to all meters of the same class. Each example is a pair of measures with an identical rhythm. The first measure demonstrates the correct or preferred way to notate the rhythm. The second measure is either incorrect, or is not preferred.

Measures with No Beat Divisions

If a measure has no beat divisions, combine the beats (this is sometimes referred to as beat multiplication):

Measures with Beat Divisions

Simple Quadruple Meters

When a measure has beat divisions in a simple quadruple meter (e.g., common time), beats 1 and 3 should be clearly visible. You do this by separating beats 1-2 from 3-4. In other words, group the first two beats and the last two beats. Never group beats 2 and 3. Notice in the “wrong” measure that the last eighth note of beat 2 is beamed to the first eighth note of beat 3, making beat 3 harder to see.

Simple Triple Meters

When a measure has beat divisions in a simple triple meter, there is more flexibility. However, the favored method is to group beats 1 and 2, or 2 and 3:

Compound Meters

When a measure has beat divisions in any compound meter, each beat should be grouped or beamed as a single unit, and separated from other beats:

Measures with Beat Subdivisions

When a measure has beat subdivisions, whether it be a simple or compound meter, each beat should be grouped or beamed as a single unit, and separated from other beats:

The rhythms for the 3/4 and 6/8 measures above are identical, but notated differently according to the meter. There are instances where a 3/4 measure may be beamed as 6/8 or vice versa, especially in modern music. But you should do this only if you intend for the music to sound as if it were in the other meter.
