1. A _____________ is a mechanical or electronic device used to keep a steady tempo. (2 points)

metronome
crescendo
ritardando
bar line
2. The term_____ means to speed up the tempo over time. (2 points)
decrescendo
score

accelerando

1. The answer is "metronome". To figure this out, you could eliminate the other options since they are not related to keeping a steady tempo. For example, "crescendo" refers to gradually getting louder in music, "ritardando" means to gradually slow down the tempo, and "bar line" is a vertical line in musical notation used to divide the music into measures. Therefore, the only appropriate option left is "metronome".

2. The term that means to speed up the tempo over time is "accelerando". To find this answer, you can eliminate the other options that are not related to changing tempo. "Decrescendo" means to gradually decrease the volume, "score" refers to a written music composition, and "rhythm" describes the pattern or arrangement of musical sounds. Thus, the correct answer is "accelerando".
