as the sun, included by
Johann Nikolaus Forkel in the
Allgemeine Musikalische Zeitung in October 1799 In 1799 the leading musical periodical of the day published a diagram created by Kollmann in the form of a "sun of composers".
Johann Sebastian Bach was at the center, the man from whom all true musical wisdom proceeded, surrounded by
George Frideric Handel,
Carl Heinrich Graun and
Joseph Haydn, and they in turn were surrounded by other composers. Kollman composed a piano concerto,
chamber music and songs. He published "The shipwreck, or the Loss of the East Indiaman Halsewell", an orchestral symphony, commemorating the 1786 loss of the
Halsewell in which about 170 people drowned. Kollmann published treatises on musical theory that build on those of
Johann Kirnberger, and take the music of J.S Bach as the basis. These include
An Essay on Musical Harmony (1796) and
An Essay on Practical Musical Composition (1799). In
An Essay on Musical Harmony he said that, when playing alone, "the organ and other keyed instruments should be unequally tempered, though not so much as some tuners do, as to produce chords which are really offensive." In
An Essay on Practical Musical Composition he argued that a concert could represent a confrontation between the parts, as in
C.P.E. Bach's "A Conversation between a Cheerful Man and a
Melancholy Man." He was the first to completely disregard the alternation between tutti and solo as the basis for a concerto's organisation, replacing it with a harmonic formula. A friendly reviewer of his
A Practical Guide to Thorough Bass (1801) began, "This work, the utility of which will be obvious to every musical reader, is conducted in that methodical and systematic plan for which all Mr. Kollmann's didactic publications are distinguished." Kollmann wrote and compiled an edition of the
Quarterly Musical Register that was published on 1 January 1812. Some sources say he may have been the translator of the work published in London in 1820 as ''On Johann Sebastian Bach's Life, Genius and Works'', from the 1802 work in German of
Johann Nicolaus Forkel. This is incorrect. ==Family==
