Time signatures and rhythm, from zero

Melody gets the glory, but rhythm is what makes people move. The good news: the notation is far simpler than it looks. Two numbers and a handful of note shapes cover almost everything you will ever play.

Note values: a system of halves

A whole note lasts four beats. Cut it in half twice and you get the quarter note — the note that usually is the beat. Halve again for eighths ("one-and-two-and…") and sixteenths. That is the entire system: every level is exactly half of the one above, which is why a steady pulse can carry any pattern.

What the two numbers mean

In 4/4 the top number says four beats per bar; the bottom says a quarter note gets one beat. So:

• 4/4 — pop, rock, funk; the accent lands on 1 (and a backbeat on 2 and 4).
• 3/4 — waltz time: ONE-two-three.
• 6/8 — two big pulses split into threes: ONE-two-three FOUR-five-six ("House of the Rising Sun").
• 5/4 and 7/8 — odd meters that feel like a limp in the best way ("Take Five", "Money").

Practising with a metronome (the way that works)

1. Open the metronome, set a tempo where you can play perfectly — slower than feels cool.
2. Choose the signature of your song and let the accented click mark the downbeat.
3. Subdivide: switch the click to eighths or sixteenths when a passage stumbles — errors hide between beats.
4. Use the tempo trainer to raise the speed a few BPM every few bars automatically. Small increments beat heroic jumps.
5. Mute beats (tap a beat dot twice) to test whether you keep time or the click does.

Rhythm and the rest of your practice

A tuned instrument and a solid pulse are the two non-negotiables of sounding good. Check your tuning in the tuner before every session — it takes thirty seconds — then give the first five minutes to the metronome. Your future recordings will thank you.
