I think I have to correct your misconception first. It’s not about adding drum beats to songs, but adding rhythm patterns to the melody.

In fact, many songs have rhythm first and melody later. This sequence relationship must also be clarified. Otherwise, how can we do it well if we can't distinguish the priorities?

When it comes to rhythm, we have to talk about what a measure is, what a single beat is, and what a compound beat is.

Bar: unit of beat. As the music progresses, strong beats and weak beats always appear in regular cycles. The part from one strong beat to the next is called a section.

Single beat: Each measure contains a strong beat of two beats and three beats, which is called single beat. For example, in 2/4 time, the rhythm pattern is "strong and weak|strong and weak|strong and weak|"

Compound beat: composed of single beats of the same type, each measure contains two or more A strong beat is called a compound beat. For example, the 4/4 beat is "strong and weak, then strong and weak | strong and weak, then strong and weak |"

Reflected on the drum beat, strong beats are usually matched with a big snare drum (bass drum), and weak beats are usually matched with a snare drum. , use the hi-hat to master the most basic rhythm notes (for example, a 4/4 hi-hat can be hit once every beat, 4 times per bar; a 6/8 hi-hat can be hit once every beat, 6 times per bar); in the case of compound beats , reflecting that the sub-strong beat also uses a bass drum. In order to distinguish it from the strong beat, it is necessary to add a bass drum sound before or after the sub-strong beat.

My level is limited, so I can only describe it in general terms.
