All of the measures in a song contain four beats. One of the measures contains a half note, a quarter note and an eighth note, and one other note. That note must be a(n)

a. half note
b. eighth note
c. dotted eighth note
d. quarter note

I belive the answer would be B
I would rewrite 1/2 + 1/4 + 1/8 =

4/8 + 2/8 + 1/8 + (answer B) 1/8 = 8/8 or one whole note 4 beats is this correct

Yes! You're right!

You're on the right track! To find the answer, let's break down the values of the notes in the measure:

- A half note is worth 2 beats.
- A quarter note is worth 1 beat.
- An eighth note is worth 1/2 beat.

So, if we add these values together:
1/2 (half note) + 1/4 (quarter note) + 1/8 (eighth note) = 4/8 + 2/8 + 1/8 = 7/8.

Since one measure must contain four beats, we need to find a note that fills in the remaining beats. In this case, the note that fills in the missing 1/8 (1 beat) to complete the four beats would be an eighth note.

Therefore, the correct answer is b. eighth note.
