By number: one after the other 8

  1. Unison Both notes are the same F, so the count is one. An odd-numbered interval runs line to line or space to space. These two notes sound one after the other: a melodic interval.
  2. Second Count G as one and go up to A: two. An even-numbered interval runs from a line to a space or a space to a line. These two notes sound one after the other: a melodic interval.
  3. Third Count E as one and go up to G: three. An odd-numbered interval runs line to line or space to space. These two notes sound one after the other: a melodic interval.
  4. Fourth Count D as one and go up to G: four. An even-numbered interval runs from a line to a space or a space to a line. These two notes sound one after the other: a melodic interval.
  5. Fifth Count F as one and go up to C: five. An odd-numbered interval runs line to line or space to space. These two notes sound one after the other: a melodic interval.
  6. Sixth Count E as one and go up to C: six. An even-numbered interval runs from a line to a space or a space to a line. These two notes sound one after the other: a melodic interval.
  7. Seventh Count D as one and go up to C: seven. An odd-numbered interval runs line to line or space to space. These two notes sound one after the other: a melodic interval.
  8. Octave From E up to the next E is eight letter names. An even-numbered interval runs from a line to a space or a space to a line. These two notes sound one after the other: a melodic interval.

By number: sounded together 8

  1. Third Count E as one and go up to G: three. An odd-numbered interval runs line to line or space to space. These two notes sound together: a harmonic interval.
  2. Fifth Count F as one and go up to C: five. An odd-numbered interval runs line to line or space to space. These two notes sound together: a harmonic interval.
  3. Second Count G as one and go up to A: two. An even-numbered interval runs from a line to a space or a space to a line. These two notes sound together: a harmonic interval.
  4. Fourth Count D as one and go up to G: four. An even-numbered interval runs from a line to a space or a space to a line. These two notes sound together: a harmonic interval.
  5. Sixth Count E as one and go up to C: six. An even-numbered interval runs from a line to a space or a space to a line. These two notes sound together: a harmonic interval.
  6. Unison Both notes are the same A, so the count is one. An odd-numbered interval runs line to line or space to space. These two notes sound together: a harmonic interval.
  7. Octave From D up to the next D is eight letter names. An even-numbered interval runs from a line to a space or a space to a line. These two notes sound together: a harmonic interval.
  8. Seventh Count E as one and go up to D: seven. An odd-numbered interval runs line to line or space to space. These two notes sound together: a harmonic interval.

By quality: above C 12

  1. Minor second One half step from C up to D flat. A minor interval is one half step smaller than the major interval of the same number.
  2. Major second Two half steps from C up to D. Seconds, thirds, sixths and sevenths are major or minor, never perfect.
  3. Minor third Three half steps from C up to E flat. A minor interval is one half step smaller than the major interval of the same number.
  4. Major third Four half steps from C up to E. Seconds, thirds, sixths and sevenths are major or minor, never perfect.
  5. Perfect fourth Five half steps from C up to F. Fourths, fifths, unisons and octaves are called perfect, never major or minor.
  6. Tritone Six half steps from C up to F sharp. Written this way it is an augmented fourth; tritone is the name for any interval of six half steps.
  7. Perfect fifth Seven half steps from C up to G. Fourths, fifths, unisons and octaves are called perfect, never major or minor.
  8. Minor sixth Eight half steps from C up to A flat. A minor interval is one half step smaller than the major interval of the same number.
  9. Major sixth Nine half steps from C up to A. Seconds, thirds, sixths and sevenths are major or minor, never perfect.
  10. Minor seventh Ten half steps from C up to B flat. A minor interval is one half step smaller than the major interval of the same number.
  11. Major seventh Eleven half steps from C up to B. Seconds, thirds, sixths and sevenths are major or minor, never perfect.
  12. Perfect octave Twelve half steps from C up to C. Fourths, fifths, unisons and octaves are called perfect, never major or minor.

By quality: above F 12

  1. Major third Four half steps from F up to A. Seconds, thirds, sixths and sevenths are major or minor, never perfect.
  2. Perfect fifth Seven half steps from F up to C. Fourths, fifths, unisons and octaves are called perfect, never major or minor.
  3. Minor third Three half steps from F up to A flat. A minor interval is one half step smaller than the major interval of the same number.
  4. Perfect octave Twelve half steps from F up to F. Fourths, fifths, unisons and octaves are called perfect, never major or minor.
  5. Major second Two half steps from F up to G. Seconds, thirds, sixths and sevenths are major or minor, never perfect.
  6. Perfect fourth Five half steps from F up to B flat. Fourths, fifths, unisons and octaves are called perfect, never major or minor.
  7. Minor second One half step from F up to G flat. A minor interval is one half step smaller than the major interval of the same number.
  8. Tritone Six half steps from F up to B. Written this way it is an augmented fourth; tritone is the name for any interval of six half steps.
  9. Major sixth Nine half steps from F up to D. Seconds, thirds, sixths and sevenths are major or minor, never perfect.
  10. Minor sixth Eight half steps from F up to D flat. A minor interval is one half step smaller than the major interval of the same number.
  11. Major seventh Eleven half steps from F up to E. Seconds, thirds, sixths and sevenths are major or minor, never perfect.
  12. Minor seventh Ten half steps from F up to E flat. A minor interval is one half step smaller than the major interval of the same number.

How this list was compiled: Interval numbers (count both notes and every line and space between; odd-numbered intervals run line to line or space to space, even-numbered ones line to space), melodic and harmonic intervals, which intervals are perfect and which major or minor, and the number of half steps in each interval from the minor second (1) to the perfect octave (12), with the tritone at 6: Robert Hutchinson, Music Theory for the 21st-Century Classroom, https://musictheory.pugetsound.edu/mt21c/IntervalsIntroduction.html and HowToIdentifyIntervals.html (sections 5.1 and 5.2), read 2026-10-01; checked against Wikipedia, Interval (music), the table of main intervals (semitones 0 to 12, minor second to perfect octave, augmented fourth and diminished fifth both called tritone), read 2026-10-01. Sharps and flats raise and lower a note by a half step: Hutchinson section 1.4, read 2026-10-01. The pitch of each note follows the treble staff as on treble-clef-notes-worksheet. Licence: own work

How it works

Forty intervals on the treble staff in four parts: eight by number written one note after the other, the same eight numbers sounded together, then the twelve intervals from minor second to perfect octave above C and above F.

Read the full guide

Name an interval in two steps

First the number: count the lower note as one and count every line and space up to the upper note. C up to E is a third. Then the quality: count the half steps. Four half steps make a major third, three a minor third. Unisons, fourths, fifths and octaves are perfect, and six half steps make a tritone.

Print it blank, numbered or as a key

Press Print this worksheet. Blank leaves room to write each answer under its pair of notes. Numbered puts a number under every pair and adds a line for each answer. Named is the answer key. Quiz yourself asks one pair at a time.

  • Odd-numbered intervals run line to line or space to space; even-numbered ones run from a line to a space.

Questions and answers

How many half steps are in each interval?

Minor second 1, major second 2, minor third 3, major third 4, perfect fourth 5, tritone 6, perfect fifth 7, minor sixth 8, major sixth 9, minor seventh 10, major seventh 11, perfect octave 12.

What is the difference between a melodic and a harmonic interval?

In a melodic interval the two notes sound one after the other and are written side by side. In a harmonic interval they sound together and are written one above the other.

Does this music theory intervals worksheet have an answer key?

Yes. Press Print the answer key, or pick Named before you print: every pair of notes has the name of its interval written under it.
