Toe the line

Toe the line is a song performed at a fast tempo of 190 BPM.

The harmony of Toe the Line is primarily centered on A♭ major, employing a combination of diatonic chords, modal interchange, and a brief modulation to C major. The harmonic language relies on extended sonorities (maj7, m7, 9, and suspended chords), which contribute to its contemporary character and smooth, refined sound. Particularly noteworthy is the use of modal interchange from C major, especially through the appearance of B♭ minor (ii of A♭ minor and ♭VII of C), which introduces a darker harmonic color before returning to the tonal center of A♭ major or modulating to the following section. The progression alternates between stable tonic functions (A♭maj7) and predominant chords such as Fm7 and Dm9, while suspended dominants and added tensions soften the effect of traditional harmonic resolutions.

The modulation to C major begins with a tritone substitution dominant (subV7/I), leading to a ii7–V7–Imaj7 progression. However, rather than resolving conclusively to the tonic, the progression moves to a deceptive resolution on vi7 (Am7). This chord is then transformed into A7 through chromatic alteration, allowing it to function as subV7/I and preparing the chromatic return to A♭ major.

The song starts with an introductory section, followed by a melodic bassline. It then transitions into a short walking bassline that spans six frets before returning to the introduction. The piece continues with a bass solo section, where the intricate harmony supports the performer, allowing them to play a variety of fast arpeggios.
