Strong and weak beats
Recognise which beats of a bar carry weight, and how the bass relates to the drums.
The beats in a bar are not all equal. Some carry more weight, and a bassist feels this all the time.
Strong and weak
Inside a bar, some beats are strong and others weak:
- in 4/4, beat 1 is the strongest and beat 3 is medium-strong; beats 2 and 4 are weaker;
- in 3/4: strong, weak, weak;
- in 2/4: strong, weak.
Playing a beat a little louder than the others is called an accent.
Bass and drums
In much popular music the drums put the kick drum on or around beats 1 and 3, and the snare on 2 and 4. Snare hits on 2 and 4 are called the backbeat. The bass very often plays the root of the chord on beat 1, the moment the harmony is defined, and lines up its rhythm with the kick drum.
These are common tendencies, not rules. Moving accents away from the strong beats is syncopation, which comes in Module 11.
Play quarter notes on the open A and accent beat 1 (play it a little louder) for 4 bars. Then accent beats 2 and 4 instead and notice the different feel.
