Interval Identification | Intervals Of A Third (3 of 10)
Similar to what we learned in the previous video about intervals of a second, an interval of a third can also be either Major or minor depending upon the amount of steps separating each note.
Minor Third Intervals
For example, an interval of a minor third occurs when two notes are separated by the distance of three consecutive half steps.
Now, we know that a whole step is essentially the same as two consecutive half steps. Therefore, if two half steps equals one whole step, then three consecutive half steps may also be looked at as being comparatively the same as the combination of one whole step and one half step.
Let's use this pattern of steps to figure out what an interval of a minor third above the note A is.

A whole step above the note A is the note B,

and a half step above the note B is the note C.

As you can see, an interval of a minor third above the note A is the note C.
By following this pattern of steps, you will be able to figure out what an interval of a minor third above any note is.
Major Third Intervals
As mentioned in the opening video of this series, an interval of a Major third occurs when two notes are separated by the distance of four consecutive half steps. Knowing that four half steps is comparatively the same as two whole steps, let's figure out what an interval of a Major third above the note G is.

Starting on the note G, one whole step takes us to the note A.
