Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. The G

G minor has been considered the key through which
Wolfgang Amadeus Mozart best expressed sadness and tragedy,[1] and many of his minor key works are in G minor, such as
Piano Quartet No. 1 and
String Quintet No. 4. Though Mozart touched on various minor keys in his
symphonies, G minor is the only minor key he used as a main key for his numbered symphonies (
No. 25, and the famous
No. 40). In the
Classical period, symphonies in G minor almost always used four
horns, two in G and two in B♭ alto.[2] Another convention of G minor symphonies observed in Mozart's No. 25 and Mozart's No. 40 was the choice of
E-flat major, the subdominant of the relative major B♭, for the slow movement, with other examples including
Joseph Haydn's
No. 39 and
Johann Baptist Wanhal's G minor symphony from before 1771.[3]
^Hellmut Federhofer, foreword to the
BärenreiterUrtext edition of Mozart's Piano Quartet in G minor. "G-Moll war für Mozart zeitlebens die Schicksaltonart, die ihm für den Ausdruck des Schmerzes und der Tragik am geeignetsten erschien." ("G minor was, for Mozart, the most suitable fate-key throughout his life for the expression of pain and tragedy.")
^H. C. Robbins Landon, Mozart and Vienna. New York: Schirmer Books (1991): 48. "Writing for four horns was a regular part of the Sturm und Drang G minor equipment." Robbins Landon also notes that Mozart's No. 40 was first intended to have four horns.
