Answer:
Within a measure of three counts, to change the note that gets one beat/count into an eighth note, means that a full measure would have three eighth notes (1,2,3). Likewise six sixteenth notes (dividing the eighths, 1& 2& 3&) are needed for a full measure.
Brainiest please :D
If people were too poor to own instruments, most people could use buckets as drums , glass jugs to make beats , their hands and feet to also make beats , and use their voices to sing. I tried my best , hope this helped!
