Did you miss me?
I returned to let you know that metronome manufacturers often place tempo words on metronomes as suggested tempo-range parameters.
In short, do not trust these tempo suggestions as concrete. Metronomes have evolved and improved as a result or advances in technology.
Metronome with tempo ranges written on the metronome are limited by its specific design. Due to the limited area to place words on the metronome, BPM ranges are approximate. Opinions vary greatly and as you have learned, all tempi are open to interpretation.
