How it works
A 63 BPM metronome clicks the Andante moderato in the slow movement of Beethoven's Ninth Symphony. The table of movements in Wikipedia's article on the symphony marks it quarter note = 63, in 3/4: one click to each beat.

Start
Tap the pad, or press Space. The 63 comes as equal clicks, so the three beats of that movement's bar are left for you to count. Another tap on the pad ends it.
Change the tempo
Tap the number under the pad and type a tempo, or use minus and plus. Three presses of minus give 60, the mark the same table sets over the Adagio that opens the movement.
Questions and answers
Is 63 BPM lento, adagio or andante?
Adagio or Andante, no longer Lento. Wikipedia's list of tempo markings ends Lento at 60; Largo, Larghetto and Adagio run to 66, Adagietto to 80, Andante to 108. Its Andante moderato only starts at 80: the figures, it warns, are very rough.
Why does a wind-up metronome have 63 but not 62 or 64?
Its usual scale has begun to climb in threes. Wikipedia's Metronome article gives the most common arrangement as 56, 58, 60 and then 63, 66, 69, 72, which makes 63 the first of the threes. Dials differ, and this pad plays 62 and 64 too.
What is dotted quarter note = 63 in 6/8?
Sixty-three beats a minute with three eighth notes inside each, 189 eighth notes a minute by our sum. This page clicks the beat alone. To hear the eighth notes too, open this site's 6/8 metronome, which counts the dotted quarter, and type 63.
Why can't I hear the metronome?
A phone is the usual culprit: its ring switch set to silent, its volume at the bottom, or Bluetooth headphones holding the click. Nothing is lost meanwhile, because the pad's two dots trade places on every beat of the 63.
