E♭ Mixolydian centre · 4/4
Clocks
Coldplay
Ostinato, repeated-note-group control, rhythmic layering, stamina.
Why this piece
The repeating keyboard figure has an immediately recognizable rhythmic identity. It is excellent for learning how a short right-hand pattern can continue while chords and bass notes change beneath it. The risk is letting the motif speed up or become uneven through repetition.
Musical profile
- Key / tonal centre: E♭ Mixolydian centre
- Meter: 4/4
- Suggested version: Original-style piano riff with a simplified supporting bass.
Representative harmony
Main riff: E♭ – B♭m – Fm; D♭ in the B♭ minor chord gives the music its modal color.
Practice loop
What to listen for
Work from chord inversions rather than isolated notes: E♭ (G–B♭–E♭), B♭m (F–B♭–D♭), Fm (F–A♭–C).
What to learn
Isolate the riff and mark its recurring accents. Count a regular four-beat pulse beneath the repeated figure rather than treating each new group of notes as a new downbeat. Introduce left-hand chord roots only after the right-hand pattern is stable. Notice how the same figure can produce a different musical effect over different bass notes.
Practice checkpoint
Maintain the riff for a minute at a consistent tempo, then change left-hand harmonies without altering its timing.

Target: Keep a three-note grouping from resetting your four-beat sense.

Use this only when it addresses the current bottleneck. Skip it when the skill is already ready.
Steps
- Tap four quarter-note beats while saying a continuous stream of eighth notes:
1 & 2 & 3 & 4 &. - RH repeats a three-note cell (for instance,
G4–B♭4–E♭5) as uninterrupted eighth notes. Since a bar has eight eighth notes, each new bar starts on a different position in the cell. - Add an LH bass note on beat 1 of every bar. Change the bass after two bars without changing the RH rhythm.
Ear task: Notice the accent shifts created by the repeated three-note cell.
Transfer: Learn the actual Clocks riff from your chosen score and distinguish its accents from the four-beat meter.
Drill checkpoint: Maintain the cell and four-beat metronome for 45–60 seconds without adding or losing an eighth note.
