Table one lists intervals of musical pitch frequently encountered in the music of the Western world. Within each box are an abbreviation for the interval's name, and the number of semitones it contains. For instance, the diminished fifth can be written dim 5th, and it contains 6 semitones. Some combinations of terms are not used, such as minor fifth or perfect sixth. Note the superscript 2 for doubly augmented or diminished.

table one	second	third	fourth	fifth	sixth	seventh	octave
doubly augmented	aug2 2nd 4	aug2 3rd 6	aug2 4th 7	aug2 5th 9	aug2 6th 11	aug2 7th 13	aug2 8ve 14

major	maj 2nd 2	maj 3rd 4			maj 6th 9	maj 7th 11
perfect			per 4th 5	per 5th 7			per 8ve 12
minor	min 2nd 1	min 3rd 3			min 6th 8	min 7th 10
diminished	dim 2nd 0	dim 3rd 2	dim 4th 4	dim 5th 6	dim 6th 7	dim 7th 9	dim 8ve 11
doubly diminished	dim2 2nd −1	dim2 3rd 1	dim2 4th 3	dim2 5th 5	dim2 6th 6	dim2 7th 8	dim2 8ve 10

Larger intervals can of course be defined. A ninth is an octave plus a second; inclusive numbering of the notes within an interval leads to the perhaps surprising result 9 = 8 + 2. Similarly, a tenth an octave plus a third (10 = 8 + 3), et cetera. Also possible are intervals that are augmented or diminished more than twice.

The smallest diatonic interval, the unison, is formed by two notes of the same scale degree in the same octave. It is not listed in the tables on this page because the two notes almost always have the same accidentals, in which case the interval is perfect. Moveover, outside of strict polyphony there is often no clear indication of which note of an imperfect unison is intended to be higher, with the result that an augmented unison is arguably the same as a diminished unison. A similar observation applies to the second when diminished one or more times.

Seconds, thirds, sixths and sevenths, ninths, and tenths can never be perfect; while unisons, fourths, fifths, octaves, and elevenths can never be major or minor.

If an interval is larger than a unison but smaller than an octave, then it can be inverted when the upper note is lowered by one octave, or the lower raised by one octave. The interval's name is converted as in table two:

table two
second	↔	seventh
third	↔	sixth
fourth	↔	fifth
perfect	↔	perfect
major	↔	minor
augmented	↔	diminished
doubly augmented	↔	doubly diminished

For instance, a diminished third becomes an augmented sixth when inverted, and a perfect fourth becomes a perfect fifth. The notion of inversion is ambiguous for the unison, or for intervals that are more than a seventh.

Some of the interval tables below employ double flats and double sharps. This reveals an inconsistency in musical notation: the double flat does not have a special symbol, but the double sharp does, and it resembles the letter x.

Most computer fonts render the single flat, the natural, and the single sharp decently, but not always attractively. Meanwhile, many computer fonts render the double flat or double sharp disappointingly, if at all. This report skirts that problem by writing two single sharps to indicate the double sharp in most places.

Table three shows what the popular encoding Unicode offers in this regard. Glyphs can vary from one font to the next.

table three
name	code	glyph
double flat	𝄫	𝄫
single flat	♭	♭
natural	♮	♮
single sharp	♯	♯
double sharp	𝄪	𝄪

The following sequence reveals how well or poorly the symbols are rendered in the user's browser:

Table four lists intervals between notes that are natural or singly sharped or flatted; two notes with the same letter name are presumed to be approximately 12 semitones apart. The table is preceded by an excerpt showing how to use it: if B-flat is the lower note of an interval, and C-natural the upper, the interval must be a major second.

			upper note of interval

Table five extends table three by adding notes that are doubly sharped or flatted, with the resultant increase in multiplicity of augmentations and diminutions.

On a separate page is table six, which incorporates triple accidentals.
