Chicago's original version of "Twenty Five Or Six To Four" is a classic rock track known for its driving rhythm, iconic riff, and energetic feel. The song features prominent guitar work, making it a favorite for beginner and intermediate players to learn.
The song uses accessible open chords, with the main progression moving through Am, G, F#, F, and E in the intro and bridge. Verses introduce C, Dm, F, E7, and G. The solo and outro use similar shapes, with some additional chords like D, Bm, B, Bb, and B7. Familiarize yourself with these chord shapes before playing.
A steady eighth-note downstroke strum works well for beginners (D D D D D D D D). For more feel, try emphasizing beats 2 and 4, or use a "down-down-up-up-down-up" pattern in the verses to mimic the song's rhythmic drive.
Practice moving from Am to G and down the chromatic line to F#, F, and E. Keep your fingers close to the fretboard and aim for smooth, quick transitions. Use guide fingers when possible, especially moving between Am, F, and E shapes.
Start slow, especially with the intro riff. Play one bar at a time and gradually increase speed. Pay attention to the chromatic movement in the intro and bridge. For barre chords like F and F#, use your index finger to barre and keep your thumb placed firmly behind the neck.
