"A few quarter notes are one beat" is the beat value of music, which can constitute the rhythm type in music. For example, if a quarter note is one beat, four beats per measure refers to 4/4 beat.

Beat is recorded as a fraction, with the numerator representing the number of beats per measure and the denominator representing the notes per beat. For example, 2/4 beat is pronounced "four-two beats", which means "one beat is made up of quarter notes, two beats per measure"; 6/8 beat, "six-eight beats", "one beat is made up of eighth notes" , eight beats per measure.” This notation is different from mathematical fractions and cannot be simplified. Otherwise, the note value and number of beats of each beat will change.

Extended information:

In the rhythm, many notes are based on one beat (this is also called "unit beat"). This is an important time period. —A beat is the basis of music, using various notes.

2/4 beat. It uses a quarter note as one beat, and each measure has 2 beats. It is called 2/4 time. There are two beats in a measure, the first beat is a strong beat and the second beat is a weak beat. A downbeat appears, then repeats itself every bar. This 2/4 rhythm is very suitable for use when marching in queue, so most marches adopt this 2/4 beat form.

3/4 beat is a quarter note, and there are 3 beats in one section, which is called 3/4 beat. That is to say, one strong beat and two weak beats appear in one section, and they appear repeatedly in each section. The first beat is a strong beat, and the second and third beats are weak beats. This is the 3/4 beat.
