What is an interval? Musical intervals are the distances between notes. They are the skips and leaps in a melody, create the pattern of a scale, and building blocks for chords.
The names of musical intervals are used to describe the distance in pitch between two notes or simply how wide the space is from one musical note to the next.
It could be debated, but these distances are actually where single notes turn into music!
Learning about intervals will help you understand many concepts in music theory much better.
Learning to identify music intervals visually and aurally and sing or play intervals on your instrument will also improve your note reading skills.

There are two ways to write or play an interval:
The smallest interval commonly used today in the music of the western hemisphere is the half step or the semitone.
On a piano it's easy to see as the distance from one key to the very next.
This is also called an interval of a minor (=small) Second.
As with the semitone (above), the whole tone (or whole step) is one small but significant interval and one of the building blocks for all the common scales.
This is also called an interval of a major (=big) second.
What are the 8 intervals in music?
Basic intervals are numbered from unison (= one or prime interval) up to an octave (= eight).
You simply count a starting note as “1”, and then count each of the staff lines and spaces to the next note.
Interval number names are:
1 = Unison/ Prime, 2 = Second, 3 = Third, 4=Fourth, 5=Fifth, 6 = Sixth, 7 = Seventh, 8 = Octave.
Compound intervals are musical intervals larger than an octave; 9th, 10th, 11th, 12th and 13th.
What are the 5 types of intervals?
Intervals are named after their number (as you saw above) but also what is called quality.
The qualities are explaining exactly how large or small each interval is.
Quality names are:
So, each basic interval (if found on the white keys on the piano or using no sharps or flats) may have different qualities:
By using accidentals (sharps and flats), the intervals can also be changed to become even larger or smaller! Read more about the 5 types of intervals here.
It is a very good idea to practice to listen to and differentiate the different intervals in music examples.
This is especially useful when you want to write down a melody you hear, or to be able to imagine how a melody sounds only by reading the notes.
Singing the intervals (even if it sounds terrible!) also helps your listening, or inner hearing, so, sing along! :)
