150 BPM Metronome
This page opens a working metronome at 150 BPM. Each click arrives every 400 milliseconds (0.4 seconds), which the Italian tempo scale calls Allegro. Press start, then change the tempo or the time signature whenever you want — nothing here is locked.

Tempo facts
How fast is 150 BPM?
A metronome set to 150 BPM plays 150 evenly spaced clicks every minute. Here is what that works out to.
Beat interval
400 ms60000 ÷ 150 = 400 milliseconds between clicks, or 0.4 seconds.Bar length
1.6 sFour beats of 4/4 at 150 BPM fill 1.6 seconds.Half and double time
75 / 300One beat per two clicks gives 75 BPM; splitting each beat in two gives 300 BPM.How 150 BPM feels
150 BPM gives a clean 400 millisecond beat — two and a half beats every second. This is the fast end of Allegro, where the pulse pushes you along rather than carrying you.
What to practise at 150 BPM
At 150 there is very little time to correct anything, so use it to confirm work already done slowly rather than to learn. If errors appear, rebuild at 75 and climb back in steps instead of repeating the mistake at speed.
Where you meet 150 BPM
150 BPM is common in punk, bluegrass and fast swing, and many Baroque fast movements are taken close to this tempo.
Half time and double time
150 BPM in half time is 75 BPM: the same music, counted with one beat for every two clicks. Double time is 300 BPM, where every beat splits into two even eighth notes. Both sit inside the 30 to 300 BPM range of this metronome, so you can switch between them and hear the difference straight away.
This relationship is the reason a written tempo and a felt tempo often disagree. Drummers and producers move between the two constantly, and it is also the safest way to learn something fast: build it at 75 BPM, keep the same subdivisions, then double the number once the movement is automatic.
