By the markings, yes: it sits in adagio and adagietto, which are among the slowest bands in common use — only largo, lento and larghetto are below them. By practice-room standards it is not slow at all, because slow practice for a difficult passage often means 50 or 60 per cent of the target and the target is frequently well above 140. What 70 reliably is, is slow enough to fix things and quick enough that a long phrase still hangs together as a phrase.

How do I get from 70 to full speed?

Small steps with a fixed number of clean repetitions between them. The trainer on this page does exactly that: give it a start, a step of 4 BPM, a bar count of 8, and a ceiling, and it climbs on its own so you never stop to change a number. The rule that matters is not the size of the step, it is that a step you cannot play cleanly means going back down, not pushing through.

What subdivision should I use at 70?

Eighths for almost everything. The beat is 857 milliseconds long, which is more than enough room to arrive late at the halfway point without noticing. If the music itself is in sixteenths, use sixteenths — 280 clicks a minute is dense but perfectly countable at this tempo, and matching the click to the fastest note in the passage is the point of the exercise.

70 BPM Metronome

← All tools

70 BPM is where two markings overlap — adagio runs 66 to 76, adagietto 70 to 80 — and where a lot of practice actually happens, because 70 is exactly half of 140. Halving a tempo is the oldest trick in the practice room and the only one that changes nothing but the clock: the same notes, the same subdivision, the same fingering, at a speed where you can see what your hands are doing. The metronome below is set to 70.

Swing Eighths or triplets only

Subdivision clicks are quieter and higher than the beat, so the pulse stays the loudest thing in the bar. Swing applies to eighths and triplets only, and pushes the offbeat of each pair later — 33% lands it on the triplet grid, 50% on a dotted eighth. The downbeat never moves.

How to practise at 70 BPM

Press Start and play the passage you cannot yet play, at this speed, without a single mistake. If there is a mistake, 70 is still too fast for it.
Put eighth notes under it. At 70 the beat is long enough that the halfway point is genuinely uncertain, and an eighth-note click removes the guess.
When four passes in a row are clean, use the tempo trainer rather than typing a new number: start 70, step 4, every 8 bars, stop at whatever the piece is marked. The climb is gradual enough that no single step feels like a jump.
If the piece is marked around 140, remember that everything you play here is the same music at half speed. Count the subdivision you will need at 140, not the one that is comfortable at 70.

The tempo a fast passage gets slowed down to

Halving is the practice tempo that needs no arithmetic and introduces no error. Take a passage marked 140 and play it at 70 and every relationship inside the bar is preserved exactly — a sixteenth is still a sixteenth relative to the beat, the accents fall in the same places, the bowing or the picking pattern is identical. Nothing has to be re-learned on the way back up, which is not true of the other common shortcut, which is to play it at whatever speed feels safe and quietly simplify the hard bar.

What halving buys you is time to notice. At 140 a sixteenth note lasts 107 milliseconds, which is under the threshold at which most players can consciously place a note; you are executing a pattern, not making decisions. At 70 the same note lasts 214 milliseconds and you can hear whether your third finger is landing with the beat or just after it. The mistake is not slow practice — it is slow practice that never gets used, so decide before you start what you are listening for.

Adagio, adagietto, and how far a marking is from a number

Adagio's band is 66 to 76 and adagietto's is 70 to 80, so 70 BPM is both. The -etto is a diminutive: an adagietto is a little adagio, and by convention a little adagio is a slightly quicker one, the same way a larghetto is quicker than a largo.

The most famous adagietto in the repertoire shows how loosely any of this maps onto a number. The fourth movement of Mahler's Fifth Symphony is headed Adagietto, sehr langsam — two words and no number — and recordings of it run from around seven minutes to over twelve — nearly a factor of two, from conductors who all read the same word on the same page. If you ever wondered whether a tempo marking is a suggestion, that is your answer. It tells you what kind of thing this is. The number you settle on is a decision you still have to make.

What 70 BPM works out to

Every number below follows from one division: sixty seconds over 70 beats. It is worth knowing the sixteenth-note figure before you decide a passage is playable — that is the rate your hands actually have to move at, not the tempo on the page.

Note value	Per minute	One lasts
Quarter note — the beat	70	857 ms
Eighth note	140	429 ms
Eighth-note triplet	210	286 ms
Sixteenth note	280	214 ms
Bar of 4/4	17.5	3429 ms

Two tempos on this site are one arithmetic step away: 140 BPM is twice this. Practising a passage at the slower one and hearing it at the faster one is the same notes at the same subdivision, counted differently.

Where 70 BPM falls in the Italian markings

70 BPM is covered by two words at once, Adagio and Adagietto. Overlap is normal and is not a defect of the system: these words were in use for a century and a half before Maelzel's metronome existed, and they describe a character — how the music carries itself — with speed as a consequence. The bands below are the ones the standard reference tables give.

Marking	Sense	BPM	Tempo pages in this band
Larghetto	rather broadly	60–66	60
Adagio	slowly, with ease	66–76	70
Adagietto	a little adagio	70–80	70, 80
Andante	at a walking pace	76–108	80, 90, 100
