How it works
A 48 BPM metronome clicks at the top of Largo on one dial: a present-day Japanese metronome pictured in German Wikipedia's Tempo article prints Largo over 44 to 48 and begins Lento there. Roughly placed bands, by its own account.

Start
Tap the pad, or press Space, and 48 begins: every click the same, two equal dots taking turns, no first beat picked out. One more tap ends it.
Change the tempo
Tap the number under the pad and type a tempo, or press minus and plus. On the commonest wind-up scale, set out in Wikipedia's Metronome article, 48 is a notch between 46 and 50. Double time, 96, has a page of its own; half time is 24, and this field takes it.
Questions and answers
How many BPM is 48 on a metronome?
48. The number on a metronome is the tempo itself: German Wikipedia's Tempo article says the metronome number gives the number of beats in a minute. At 48 that is four beats every five seconds exactly, by our sum.
Is 48 BPM largo or lento?
Wikipedia's list of tempo markings allows both, as very rough figures: Largo from 40 to 66, Lento from 40 to 60. A 20th-century German dial and a 19th-century French one, pictured in German Wikipedia, print Largo alone, over 40 to 60 and 42 to 70.
Is 48 BPM adagio?
It can be. Adagio and Larghetto run 44 to 66 in Wikipedia's list of tempo markings, and Adagietto 46 to 80. Grave stops at 40 and Andante starts at 56, so 48 is neither. No word fixes a number, the list adds.
How do I set a metronome to dotted quarter = 48?
Leave this pad at 48: each click is then a dotted quarter note, and its three eighth notes last 416.7 ms each, by our division. To hear them, open the 6/8 metronome, which counts the dotted quarter, and type 48: 144 clicks a minute.
Why can't I hear the metronome?
Clicks at 48 come more than a second apart, so let two go by before deciding. If nothing sounds, the usual causes on a phone are the ring switch, the volume or a Bluetooth device. The two dots keep taking turns either way.
