Watch the Sonora Spring: Pre-Chorus 1 online guitar lesson by John Jorgenson from Gypsy Jazz Journeys: Sonora Spring
Here's the first phrase of the pre-chorus. Again, like the verse, it starts with the same chord voicing as the rhythm part: Cmaj7. I sweep up again to the melody note, which is on the 3rd fret of the B string, but not as hard as the last one - softer to match the dynamic of the song at this time. Then we go onto the melody, which is on the A and D strings, then a slide between the 2nd and 4th fret and some vibrato to arrive at the D6 chord. We end the phrase by going back down to the A at the 2nd fret of the D string, adding vibrato.
