What a metronome measures
Beats per minute describes the spacing of a regular pulse. At 60 BPM, beats arrive once per second; at 120 BPM, twice per second. The click can expose rushing and dragging, but it cannot judge pitch, fingering, tone, relaxation, or whether your chosen beat unit matches the notation. Decide what note value receives each click before playing.
Two worked examples
- Set 60 BPM and count 1–2–3–4 for two measures. Play C–Am–F–G with one chord per click, listening for each attack to coincide with the pulse.
- For an eighth-note passage, set 72 BPM with the quarter note as the beat. Say “one-and-two-and” and place two even notes between clicks. If notes bunch together, reduce the tempo.
A practical method
First play slowly without a click and settle the movement. Next, choose a tempo at which you can hear and correct errors. Work on a short section, changing speed only after a controlled attempt. Clef's editorial example is to note the date, passage, starting tempo, and one observation; it is a tracking suggestion, not a guaranteed improvement formula.
Limits
Following a click is not the same as playing expressively or accurately. A continuous click may conceal whether you can maintain an internal pulse, while excessive speed can reinforce uneven movement. Alternate clicked and unclicked attempts, record yourself when possible, and treat BPM as descriptive information rather than a score. Stop if matching the click creates strain.
| Observation | Adjustment | Listen for |
|---|---|---|
| Notes arrive late | lower BPM | comfortable preparation |
| Notes rush between clicks | subdivide aloud | even internal spacing |
| Pulse disappears without clicks | alternate click on/off | continued internal count |
