The music term calculator help you determine an interval between two notes. To discover an interval between two pitches, select from sounds in ripe octaves and find the an easy and compound name for any kind of distance better than one octave. If you desire to understand an interval between notes, the calculator will certainly differentiate in between enharmonic equivalents (like "C#" and also "Db", which denote the very same sound) and also give you additionally diminished and augmented intervals.

Intervals are among the straightforward concepts the music theory. They space the structure blocks that scales and also chords, i m sorry in turn make up melodies and harmonies. Understanding and also recognising castle is necessary for musicians, as it makes it much easier to play by ear, write melodies, communicate with various other musicians, and understand more complicated ideas in music theory.

In the text below, you'll discover a music intervals chart, and also a collection of instructions on how to use the music term calculator. You'll learn what's the the smallest musical interval, just how to find interval quality, and how to discover the distance in between two notes, choose from F to C.

Music term - definition

A music interval is the distance between two notes, i m sorry can additionally be defined as the difference in pitch in between two sounds. In physical terms, the is the ratio in between the vibrational frequencies that notes.

Notes in music theory space sounds with determined frequencies. In English speaking countries, sounds in the C major scale (the white tricks on a piano) are called with the an initial seven letter of the Latin alphabet:

C, D, E, F, G, A, B

Another usual system because that naming this sounds is solfège, which supplies the syllables:

Do, Re, Mi, Fa, Sol, La, Si

Intervals may be counted in semitones. A semitone is the smallest unit that a musical distance that is generally used in western music. It is the street between any type of two notes on surrounding keys (on a piano) or frets (on a guitar).

What is an octave?

Let's have a look in ~ a piano keyboard:

On white keys we have actually the sound C, D, E, F, G, A, and B. You can see that after B, girlfriend have another C, then D, and also so the pattern repeats.

So, how execute we differentiate in between two Cs if we need to? We usage the scientific notation - we add a number alongside the letter, for this reason we have C1, C2, C3, etc.

The term (distance) between two notes, e.g., between C1 & C2 or F3 & F4, is called an octave. When we walk an octave up, us double the frequency. Because that example:

A4 = 440 Hz

A5 = 880 Hz

A6 = 1760 Hz

Accidentals in music

We've covered the white keys, however what about the black ones?

We use the sharp "♯" and also flat "♭" signs, together with the letters, to designate the sounds on the black color keys. Sharp raises the keep in mind by a semitone (the the smallest musical interval), if a flat lowers the by one.

The black crucial between C and also D deserve to be called C# or Db. C# and also Db space the very same sound, however which name you have to use relies on the music context.

If us play each note on a piano one by one indigenous left to right, we gain 12 tones which make up the chromatic scale:

C C#/Db D D#/Eb E F F#/Gb G G#/Ab A A#/Bb B

In this scale, the distance between any kind of two surrounding notes is one semitone. E and also F and also B and C room the two pairs the white keys which don't have a black vital between them, as they room a semitone personally anyway.

Musical intervals chart

Ok, this is the interesting moment where you find out the surname of the intervals!

The the smallest musical expression (not counting a unison/prime, which is wherein the notes room the same, e.g., in between C1 and also C1) is the young second. It's equal to one semitone, for this reason a minor 2nd is, for example, in between G and Ab. If you go from C come D, you will certainly go increase by a ton (two semitones), i m sorry is known as a significant second. Below you deserve to see the names the the intervals increase to and also including one octave and also the corresponding variety of semitones.

*A tritone is also called one augmented 4th or a diminished fifth (depending on the context).

How to usage the music term calculator?

We divided the music expression calculator right into two parts. The first one deals with intervals between pitches, and the second - note as units of music theory.

What is the difference?

You must use the an initial one once you want to know an interval between two sounds. For example, between a piano vital which we represent by C, and also another one denoted through C♯ or D♭. The interval between the sounds developed by these two secrets is a boy second. Us don’t use the augmented and also diminished intervals here, as you would never talk about an augmented element if somebody sang 2 sounds come you and asked what interval that is.

BUT the interval between C and C♯ IS not a minor 2nd (but the one in between C and D♭ is). As soon as you want to uncover the interval between notes native their letters or icons on a staff, you have to use the “between notes” part of the calculator. It will tell you the interval in between C and C# is an augmented prime. Notes often appear in a music context favor a range or key, i beg your pardon is when diminishing and augmenting matters.

If you desire to discover an interval in between two notes (e.g., on a music theory test 😉), leave the interval type in the calculator together the default and also simply pick the names of the notes. Remember note 1 needs to be the lower than note 2. Walk to the advanced mode if you desire to check out the corresponding number of tones and semitones.

If you desire to recognize an interval between two sounds:

Change the "interval type" in the first field.Choose the note and also octave whereby we represent the very first sound.Choose the note and also octave whereby we represent the second sound.At the bottom of the music expression calculator you'll check out what's the interval between the 2 pitches. If you want to know the number of semitones and also tones that comprise the expression - switch the advanced mode.


Intervals bigger than an octave are referred to as "compound intervals". They have the right to be thought of together a certain variety of octaves + the staying interval.

For intervals with between 13-28 semitones, you'll check out both the straightforward and the compound name.

Intervals through more than 28 semitones (major seventeenth) will only have actually a link name, together they are really rarely known by noþeles else. So, because that example, you'll check out "two octaves to add a fifth" instead of a 19th.

Determine an interval in between two pitches

Learn the number of semitones in all of the an easy intervals. Then count how many keys top top a piano (or frets ~ above a guitar) you need to go from keep in mind 1 to keep in mind 2.

Example: you want to recognize the interval between sounds corresponding to secrets C and also E.

First, count the distance in between keys - there space 4 semitones. Then you look at the musical intervals chart and also see the 4 semitones exchange mail to a significant third.

Alternatively, you can go from keep in mind 1 to keep in mind 2, naming every the intervals instead of count semitones.

Determine an interval in between two notes

Intervals is composed of a number (second, third, fourth) and also its quality (minor, major, perfect). To examine the interval between two notes:

Identify the number - erase the accidentals (C# becomes C, Bb i do not care B, etc.), then counting the actions as if we were utilizing a C-major scale. For example, from G# come E, you count:

G - 1, A - 2, B - 3, C - 4, D - 5, E - 6

E is the 6th note, therefore the expression is a sixth.

Identify the interval quality by counting the semitones between the notes, tho ignoring the accidentals.

For example, we have 9 semitones in between G and E (check with a keyboard), which renders it a significant sixth.

Adjust because that accidentals:

If the notes have no accidentals or they room the very same in both notes (F# and also G#, Bb and Ab, etc.), the interval from step 2 remains the same.


"♭" beside the reduced note increases the interval, "♯" decreases it;"♭" alongside the greater note reduce the interval, "♯" boosts it.

Now, if girlfriend decrease an interval through a semitone:

If it's major, it alters to minor;If it's boy or perfect, it alters to diminished; andIf it's diminished, it alters to doubly diminished.

If you increase one interval through a semitone:

If it's minor, it changes to major;

If it's major or perfect, it alters to augmented; and

If it's augmented, it changes to double augmented.

Let's uncover an interval between A# and C:

Count the measures for the notes without accidentals:

A - 1; B - 2; C - 3 - it's a third.2. In between A and also C there room 3 semitones - it's a minor third.3. We need to decrease the interval because of the sharp sign. The minor 3rd becomes a diminished third.

How to get from F to C - examples

From F come C we count:

F - 1, G - 2, A - 3, B - 4, C - 5

We perfect at 5, therefore the expression is a fifth. There are 7 semitones (check top top a keyboard), therefore it's a perfect fifth. No accidentals here, therefore it stays perfect.

From C to F we count:

C - 1, D - 2, E - 3, F - 4

Fourth. 5 semitones - it's a perfect fourth.

C to F#:

At first, we overlook the accidental:

C - 1, D - 2, E - 3, F - 4

We understand the number - fourth. However we need to go one semitone higher to reach F#. We have to augment the perfect fourth, for this reason the interval will certainly be the augmented fourth.

C come A:

C - 1, D - 2, E - 3, F - 4, G - 5, A - 6

It's a sixth. 9 semitones do it a significant sixth.

C to Ab:

At first, we overlook the accidental and count:

C - 1, D - 2, E - 3, F - 4, G - 5, A - 6

It's a sixth. In between C and A there room 9 semitones, therefore it's a significant sixth. There's a flat sign next to the greater note, for this reason we have to decrease the interval through a semitone. Therefore, it will be a minor sixth.

Now other tricky: F# to Bb:

We count the measures for the note without accidentals:

F - 1, G - 2, A - 3, B - 4

It's a fourth.

6 semitones in between F and B indicate it's a tritone. Tritone, depending on the context, is dubbed an augmented 4th or a reduced fifth. We understand from action 1 the it needs to it is in a fourth, therefore we have actually an augmented fourth.

# next to the reduced note method we need to decrease the semitone. It becomes a perfect fourth. B next to the higher low means we need to decrease that one much more time. Perfect transforms to diminished, therefore we finish up v the diminished fourth.
