click here to listen to a keyboard play the notes starting at a and ending at e. each note is a half - step above the previous note. how many half - steps are there between a440 and the e above it? done
Answer
Explanation:
Step1: Count the half - steps.
Starting from A and going to E, we count the number of half - steps between them. From A to B is 2 half - steps (A - A# - B), from B to C is 1 half - step, from C to D is 2 half - steps (C - C# - D), from D to E is 2 half - steps (D - D# - E).
Step2: Sum up the half - steps.
$2 + 1+2 + 2=7$
Answer:
7
