Instrument
Wasn't the pentachord also a classical era instrument? Karl Abel composed for the Pentachord I believe. - 74.13.5.179 13:23, 6 April 2007 (UTC)

Transposablity of Pentachords
From the article,


 * A diatonic scale comprises five non-transpositionally equivalent pentachords rather than seven because the Ionian and Mixolydian pentachords and the Dorian and Aeolian pentachords are intervallically identical (CDEFG=GABCD; DEFGA=ABCDE).

is challenged with the "original research?" tag.

The assertion in the text is a commonplace in music theory, e.g., this garden-variety user page. - JacquesDelaguerre (talk) 20:20, 12 October 2010 (UTC)
 * The problem was with the larger context of the paragraph, which includes "any five pitch classes, regarded as an unordered collection". As such, there are 21, not 7 pentachords (not necessarily with distinct intervallic content) as subsets of any set of seven pitches (including the diatonic set). The assertion in the text "is a commonplace in music theory" only under the second definition: "any consecutive five-note section of a diatonic scale". I think I have now repaired the confusion.—Jerome Kohl (talk) 21:45, 12 October 2010 (UTC)
 * Excellent, maestro! Thanks for disambiguating - JacquesDelaguerre (talk) 01:25, 13 October 2010 (UTC)

Take it down a notch. too technical even for those who know music theory — Preceding unsigned comment added by 8.225.200.133 (talk) 21:14, 3 December 2012 (UTC)

 * As far as I can see (given that this is such a small article already), this must be a nomination for deletion—at least of the second paragraph.—Jerome Kohl (talk) 17:21, 4 December 2012 (UTC)
