F7 is a dominant seventh chord consisting of four notes or steps. A major triad is formed from two connected thirds, and a minor third is added to it. The main, lower note of the chord is its first degree – the note F. It is followed by a major third, the note A, which gives the base of the chord a major characteristic. The note C takes the role of the fifth step in this chord, in combination forming a major triad through the addition of a clean fifth. The additional seventh to the main triad in this chord is the E flat (Eb), which is the highest note in the F7 chord.
Part A, repeated twice in the opening verse of “Taking a Chance on Love”, follows a recognizable chord progression. This allows the listener to perceive the song more as accessible music that is closer to pop than to intellectually loaded jazz music. The song structure of this composition reaches a higher tonally higher chord structure in Part B. It begins at 1:22 in this song (YouTube, 2010). Raising the tonality of the vocals in addition to the moving sound of the double bass gives the song a dreamy touch in this part of the song. The staccato, which in this performance appears to be the main method of playing the bassist, gives the song a sense of movement.
Tonal transitions through chord arpeggios played using the staccato method allow the performers to gracefully transition from one section of a song to another. This section of the song seems more musically complex than the repeating section A. This is probably why the musicians play it only once, ending at 1:40 when the song returns to its more standard previous form.
