What 40 BPM feels like
40 BPM is 0.67 beats per second. In the Italian tempo terms musicians use, this is Largo, which means “broadly”.
Tempos this slow are mostly used for slow practice and for slow, broad parts of classical music.
Producers use these lengths to time delay effects. For the classic rhythmic echo at 40 BPM, set the delay to the dotted-eighth value.
A steady 40 BPM click (Largo) keeps your timing even while you practise a passage at exactly this speed.
How to use it
