Sheet music has told players how fast for centuries — but until the 1800s it did so with words, not numbers. The Italian terms printed above the staff describe a character as much as a speed, and the BPM ranges attached to them are convention, layered on later by the makers of the machine this site is named for.

The conventional ranges

The table below follows the scale commonly printed on mechanical metronomes — the version most musicians first meet. Treat the edges as fuzzy: sources differ (often deliberately), and the “Sources” section at the bottom links references that disagree with each other in instructive ways.

Marking	Conventional BPM	Character
Larghissimo	under 40	as slow as it goes
Grave	20–40	solemn, heavy
Largo	40–60	broad
Larghetto	60–66	slightly less broad
Adagio	66–76	slow, at ease
Andante	76–108	walking pace
Andantino	~80–108	ambiguous — see the FAQ
Moderato	108–120	moderate
Allegretto	112–124	moderately fast, light (not on Cool Metronome’s scale)
Allegro	120–156	fast, bright
Vivace	~156–176	lively
Presto	176–200	very fast
Prestissimo	200–208+	fastest

For comparison: Dolmetsch’s music dictionary publishes deliberately wider, overlapping ranges for the same words (its Andante spans 56–88 against the 76–108 shown here, and it documents what three different metronomes printed beside each term). Wikipedia’s tempo article prints yet another set. Nobody is wrong — the numbers were never standardized.

Where the numbers came from

The mechanical metronome was patented in 1815 by Johann Nepomuk Maelzel as an “Instrument/Machine for the Improvement of all Musical Performance, called Metronome” — built on a design by Dietrich Nikolaus Winkel, whose 1814 Amsterdam chronometer Maelzel borrowed (the word “borrowed” does a lot of work there; Winkel’s contribution is documented in the Wikipedia metronome article). Maelzel’s real innovation for the history books was the numerical scale: for the first time a composer could write a number instead of hoping a word survived translation.

Beethoven took to it immediately, adding metronome marks to his already-published symphonies — and promptly demonstrating the system’s limits, since his marks are still debated as implausibly fast.

Why you should hold the ranges loosely

Guitar educator Douglas Niedt makes the point bluntly in his essay on metronome dial markings: the words and the numbers on a metronome dial have no intrinsic musical correlation — only their order is reliable. Adagio is slower than Andante; whether Adagio “is” 66–76 or 55–75 depends on the scale, the edition, the era and the piece. A Baroque Largo was quicker than a Romantic one, and * Allegro* in a Mozart overture doesn’t mean the same feet-on-the-floor speed as in a bebop head. The words tell you how the music should feel; the BPM number is one performer’s answer, not the composer’s law.

Using the chart in practice

The tempo-name label under the BPM readout on the metronome follows these conventional ranges — specifically the boundaries Cool Metronome publishes, chosen because they’re an actual maker’s dial — a rough translation layer, convenient when a score says “Andante” and you need somewhere to start. Start mid-range, let the piece argue back, and if two sources disagree about where a marking begins, they are both right.

Frequently asked questions

Is there an official BPM for Allegro?

No single authority fixes one. The familiar ranges trace back to the scale printed on Maelzel-style mechanical metronomes, and different editions, dictionaries and manufacturers assign somewhat different numbers — Dolmetsch's reference lists multiple published ranges per term for exactly this reason. Treat any chart as convention, not law; the character the word describes matters more than the digits.

What does ♩ = 120 on sheet music mean?

That's a metronome mark: the named note value (a quarter note, here) lasts exactly one beat at 120 beats per minute — half a second. Unlike a tempo word it's a precise specification, not a suggestion. Composers have written them since the metronome spread in the 1810s; Beethoven was among the first to publish metronome marks for his symphonies.

Why do different charts give different ranges for the same word?

Because the words predate the machine. Italian tempo terms described character — 'walking pace', 'cheerful' — for two centuries before anyone attached numbers, and the numbers that did get attached vary between metronome scales, editions and pedagogical traditions. Historical context shifts them further: a Baroque-era Largo sits at a different speed than a modern one.

What's the difference between Largo and Larghetto?

Largo is broad and slow; Larghetto is literally 'a little Largo' — slightly less slow, typically starting around where Largo ends on the conventional scale (~60 BPM). The diminutive -etto ending means 'somewhat less', which is also why Andantino has confused generations of students: it can mean a little faster OR a little slower than Andante, depending on the composer and period.

How fast is too fast for Prestissimo?

On the conventional metronome scale Prestissimo begins around 200–208 BPM — roughly the top of a mechanical metronome's range. Beyond that the limit is physical, not notational. This metronome goes to 300 BPM, which covers every published marking plus the upper reaches of speed-metal and drum & bass.
