, because the sixth serves as a substitution for the major seventh, thus considered a chord tone in such context.
However, Walter Piston, writing in 1952, considered that, "a true thirteenth chord, arrived at by superposition of thirds, is a rare phenomenon even in 20th-century music." This may be due to four-part writing, instrument limitations, and voice leading and stylistic considerations.

Typically, a dominant chord anticipating a major resolution will feature a natural 13, while a dominant chord anticipating a minor resolution will feature a flat 13. Since thirteenth chords contain more than four notes, in Four-part harmony">four-voice writing the root, third, seventh, and thirteenth are most often included, excluding the fifth, ninth, and eleventh . The third indicates the quality of the chord as major or minor, the seventh is important for the quality as a dominant chord, while the thirteenth is necessary in a thirteenth chord.
In modern pop/jazz harmony, after the dominant thirteenth, a thirteenth chord (usually notated as X13, e.g. C13) contains an implied flatted seventh interval. Thus, a C13 consists of C, E, G, B, and A. The underlying harmony during a thirteenth chord is usually Mixolydian mode">Mixolydian

the "most common" pitches present in V13 chord are the root, 3rd, 7th, and 13th; with the 5th, 9th, and 11th "typically omitted".Benward & Saker (2009), p.183-84. The 13th is most often in the soprano, or highest voice, and usually resolves down by a 3rd to the tonic I or i. If the V13 is followed by a I9 the 13th may resolve to the 9th.
Other thirteenth chords
These voice leading guidelines may not be followed after the common practice period in techniques such as parallel harmony
In music, parallel harmony, also known as harmonic parallelism, harmonic planing or parallel voice leading, is the parallel movement of two or more melodies (see voice leading).

and in the following example:
13th chords may less often be built on degrees other than the dominant, such as the tonic or subdominant.
While the dominant thirteenth is the most common thirteenth chord, the major thirteenth is also fairly common.Hal Leonard Corp. (2003). ''Picture Chord Encyclopedia: Photos, Diagrams and Music Notation for Over 1,600 Keyboard Chords'', p.10. . A major thirteenth chord (containing a major seventh) will nearly always feature a chromatically raised eleventh (C E G B D F A) (see Lydian mode), except for cases when the eleventh is omitted altogether. "It is customary to omit the eleventh on dominant or major thirteenth chords because the eleventh conflicts with the third," in these chords by a semitone.

of a complete thirteenth chord including ''all'' seven notes, itself, "a rare phenomenon", is a theoretical impossibility since a new thirteenth chord with a different root is produced, for example Cmaj13 (C-E-G-B-D-F-A) becomes Em139 (E-G-B-D-F-A-C) then G13 (G-B-D-F-A-C-E), and so on, when inverted.
