7/8 time Rush

Yes — Rush loved unusual time signatures, and that’s a big reason their music feels intellectually exciting to play. Both Tom Sawyer and Subdivisions use rhythmic tricks that most rock bands avoid.

Rhythm in “Tom Sawyer”

Most of the song is in 4/4 time, but Rush adds subtle rhythmic tension.

Main groove

The basic pulse is:

4/4 rock time

Count it like:

1 – 2 – 3 – 4

But the synthesizer and guitar accents often land between the beats, creating a syncopated feel.

Example of the main riff feel:

1 & 2 & 3 & 4 &

with accents off the beat.

This gives that pushing, driving energy.

The famous odd-time section

In the instrumental synth/drum break, the band briefly shifts into 7/8 time.

That means the measure contains 7 eighth notes instead of 8.

Mathematically:

7/8

Musicians often feel it grouped as:

3 + 4

Counted like:

1-2-3 | 1-2-3-4

This creates the slightly “lopsided” groove you hear before the solo.

Neil Peart locks the drums tightly to this pulse, which makes it feel natural even though it’s uneven.

Subdivisions intro rhythm

The intro of Subdivisions also plays with 7/8.

Often musicians feel it as:

2 + 2 + 3

Counted:

1-2 | 1-2 | 1-2-3

This produces the uneasy, mechanical pulse that fits the theme of suburban conformity.

Why Rush used these rhythms

Drummer Neil Peart loved progressive rock and composers like Igor Stravinsky and Béla Bartók, who frequently used irregular meters.

Odd time signatures:

• create tension

• keep musicians engaged

• prevent the groove from feeling predictable.

A neat musical insight

Even when Rush uses 7/8, they make it feel natural by grouping the beats into familiar chunks (like 3+4 or 2+2+3).

Your brain hears patterns instead of just counting numbers.

That’s why Rush songs feel complex but still groove.

🎹 Since you’re playing Rush on the Arturia keyboard and piano with GarageBand, a fun experiment is this:

Set a metronome to 7/8 and try counting:

1-2-3-4-5-6-7

Then try grouping it:

1-2 | 1-2 | 1-2-3

You’ll suddenly feel the Subdivisions pulse appear.

If you want, I can also show you something very interesting:

the hidden rhythmic trick in “Tom Sawyer” that makes the riff sound bigger than 4/4 (a polymetric illusion Rush loved). It’s subtle but brilliant.
