An interval is the space between two notes. There are two parts to naming an interval:
◦ The Quality (major, minor, perfect)◦ The Distance (2nd, 3rd, 4th, 5th, 6th, etc.)
What is an interval?
For example… *click to listen*
Think of musical intervals like measurements on a ruler.
◦ Some intervals are smaller
◦ While others are larger
Musical interval… ruler of music
The first step is to determine which of the two notes is lower.
Step 1: Lower vs. Upper Note
The next step is to count the amount of half steps (white & black keys) between the notes…
For example, there are 5 half steps between the following two notes:
Step 2: Count the half steps
F
Bb
Most white keys are 2 half steps (or a whole step) a part.
The exception to this is between:◦E - F◦B – C
Remember…
Count the amount of half steps in the following intervals:
Half Step Counting Practice
Half steps:1 2 3 4 5
Half steps:1 2 3 4 5
Half steps:1 2 3 4 5
When we count half steps… we are essentially measuring the distance between two notes◦ Just like when we measure the distance with a
ruler, we use inches
◦ In music, we use half steps instead
Half steps are like inches
Memorize the following table to determine the quality of an interval. Remember to count up from the lower note. *short hand is case sensitive*
Step 3: Name the interval
No. of half steps
Quality/Interval

Identify the following interval…Putting it together…
Step 1: Identify the lower note.

Identify the following interval…Putting it together…
Step 2: Count the half steps between the two notes…

Great Job!!!STAIR Completed
Correct!
Note reading review:
Almost, try again!
Remember to count the amount of white & black keys between each note…
Oops! Try again
Let’s review…
Almost… give it another try.
