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]

The key note, or tonic, of a piece of music is called note number one, the first step of (here), the ascending scale iii–IV–V. Chords built on several scale degrees are numbered likewise. Thus the chord progression E minor–F–G can be described as three–four–five, (or iii–IV–V). A chord may be built upon any note of a musical scale.

Methods that establish the key for a particular piece can be complicated to explain and vary over music history. [citation needed] However, the chords most often used in a piece in a particular key are those that contain the notes in the corresponding scale, and conventional progressions of these chords, particularly cadences, orient the listener around the tonic.
Although E-sharp minor is usually notated as F minor, it could be used on a local level, such as bars 17 to 22 in Johann Sebastian Bach's The Well-Tempered Clavier, Book 1, Prelude and Fugue No. 3 in C-sharp major. (E-sharp minor is the mediant minor key of C-sharp major.) The scale-degree chords of E-sharp minor are: Tonic – E-sharp minor
These chords are all borrowed from the key of E minor. Similarly, in minor keys, chords from the parallel major may also be "borrowed". For example, in E minor, the diatonic chord built on the fourth scale degree is IVm, or A minor. However, in practice, many songs in E minor will use IV (A major), which is borrowed from the key of E major.
the ascending melodic minor scale or jazz minor scale (also known as the Ionian ♭ 3 or Dorian ♯ 7): this form of the scale is also the 5th mode of the acoustic scale. the descending melodic minor scale: this form is identical to the natural minor scale . The ascending and descending forms of the A melodic minor scale are shown below:
