Questions and answers
What music is 150 BPM?
Hardstyle, in its modern form. Wikipedia's Hardstyle article says the genre sped up over the years: once 135 to 150 beats a minute, later 150 to 160. That makes 150 the one figure both ranges hold, the old top and the new floor.
Is 150 BPM still allegro?
Yes, near its upper edge: Allegro is 120 to 156 in Wikipedia's list of tempo markings, and Molto allegro or Allegro vivace 124 to 156. Vivace takes over at 156 and Presto waits until 168. Every figure is offered as a rough guide.
What is the nearest wind-up metronome setting to 150?
152. In the most common arrangement, which Wikipedia's Metronome article lists, the notches above 144 climb eight at a time (152, 160, 168), so 150 sits between 144 and 152 with no notch of its own. Not every scale follows that arrangement.
Why can't I hear the metronome?
Sound can go missing three ways on a phone: the ring switch is on silent, the volume is at nothing, or Bluetooth has sent the click to another device. The four dots light on every beat regardless, largest first.
