It is written in the key of F major and usually begins with a F major seventh or F sixth chord.
There is one flat-III (F chord) near the end, but unusually no V (A) chord.
During the solo on this track, Yngwie used F lydian for the F chord:
He explains that although the song is in the key F minor, the F minor chord never appears.
For example, the E chord barred one fret up becomes an F chord (133211).
The B major and F major chords are commonly played as barre chords, with the first finger depressing five-six strings.
The F major chord is the same shape as E major but it is located one fret further up the fretboard.
To create F minor from the F major chord (in E major shape), the second finger should be lifted so that the third string plays onto the barre.
The concerto finishes with piano solo, sadly playing low F minor chords.
After a brief period of afterglow, the work ends with two emphatic F major chords.
