What is Simple Time?

Meet Mochi 🐱 and Bao 🐼 and learn simple time signatures, the 8 grouping rules, rests, and triplets!

⏱️ What is Simple Time?

The quick way (shhh, the cheat!): if the top number of the time signature is a 2, 3, or 4, the music is in Simple Time.

πŸ”‘ The real rule: it's Simple Time when the main beat divides equally into two.

Example 1 β€” 24

In 24 there are 2 crotchet beats per bar. Each crotchet splits into two quavers β†’ Simple Time. 🎡

Example 2 β€” 22

In 22 there are 2 minim beats per bar. Each minim splits into two crotchets β†’ Simple Time. 🎡

🏷️ Describing Simple Time

Add the word Simple to how many beats are in the bar:

2Duple = 2 beats
3Triple = 3 beats
4Quadruple = 4 beats

34 = Simple Triple  Β·  22 = Simple Duple  Β·  48 = Simple Quadruple

🎡 Grouping Notes β€” The 8 Golden Rules

When we beam notes together, we follow these 8 golden rules (most of the time!). They help the reader see the beat.

1All groupings happen within the bar β€” no beams over the barline. A note held over the barline uses a tie.
2Do not group across the β€œcentre” of the bar in quadruple time. In 44 the centre is beat 3, so don't beam between beats 2 and 3 (mainly beaming β€” not minims).
3Groups of quavers and/or semiquavers are grouped into 1 crotchet beat.
4Demisemiquavers are grouped into 1 beat or half beats.
5Four quavers which could be replaced by a minim are beamed together.
6BUT, six quavers which fill a whole bar of 34 are beamed together.
7In 38, quavers and semiquavers that make a whole bar are beamed together.
8Generally use single dotted notes over ties, and avoid ties where possible (e.g. in 22 use a semibreve, not two tied minims).
🎯 Practice β€” one question per rule
🀫 Grouping Rests
1A new beat ALWAYS needs a new rest β€” so the reader can see where each beat is.
2A whole silent bar is shown with one semibreve rest (this also means 4 beats rest).
β˜…Exception In 42, a whole silent bar uses a breve rest (a breve = two semibreves).
3In quadruple time you may join two beats of rest at the start (beats 1&2) or end (beats 3&4) β€” but never across the centre (beats 2&3).
🎯 Practice β€” rest rules
πŸ–ΌοΈ Spot the Correct Grouping

Just like the exam! Tick the bar that is grouped correctly. The others break a golden rule.

3️⃣ Triplets, Quintuplets & Sextuplets
3️⃣ A triplet = play 3 notes in the time of 2 (of the same value).

So three triplet quavers take the time of two quavers, and three triplet crotchets take the time of two crotchets.

5️⃣6️⃣ A quintuplet (5) or sextuplet (6) lasts the same as 4 notes of the same value.

So a semiquaver sextuplet (6 semiquavers) = 4 semiquavers = one crotchet beat.

🎯 Practice β€” triplets & tuplets
