Theory
At last, the final week, Week 12. This week's goal is just one thing — completing a whole blues on your own. You've learned comping and you've learned soloing, and now one person moves between the two to fill twelve bars. Comping is the question, soloing is the answer — a conversation that asks with rhythm and answers with lead. Today is the first step: getting the switch from comping to solo into your hands.
The switch has two 'homes.' One is the comping home — the A7 boogie that lays the 5th, 6th, b7 on the 4th string over the open 5th-string root A. The other is the solo home — the familiar box 1 around fret 5. The two homes sit close together, so you can move between them without shifting your hand much. When comping, your hand stays near the open strings; when moving to solo, it climbs a touch up to box 1. Once it's familiar, the two homes feel one step apart.
What matters is that the groove doesn't break at the moment of the switch. If you stop comping and hesitate — 'okay, now solo!' — the conversation snaps. The last beat of the comp and the first note of the solo must ride the same flow for the conversation to feel natural. At first it's fine if the timing wobbles a little during the switch. As long as the shuffle groove you tap with your foot never stops, the solo notes just settle on top of it. Today, at BPM 80, shuffle, slowly smooth out just that seam of comping one bar and moving into the solo.
▶ Over the open 5th-string root A, moving the 4th string through 5→6→b7 makes the A7 boogie comp.
See it
Now look again at the solo home where the answer lives, on the fretboard. The comp rang near the open strings, but the solo comes out of box 1 around fret 5. The two homes are just a few frets apart — keep the right-hand groove and only move the left hand.
▶ This is the box 1 where the answer lives. From the comping home, just raise the left hand to around fret 5 and you're here.
When your hand rises and falls naturally between comping and this box 1, question and answer join into one.
Today's practice
0–10 min · Warm-up BPM 60. First take out just the comp and practice it. Over the root A, roll the 5→6→b7 boogie slowly with a shuffle groove.
▶ BPM 60, shuffle. The A7 boogie moving 5→6→b7→6 over the root A. Get the right-hand groove into your body first.
10–20 min · Brain training (today's target = comp↔solo switch) Before real practice, draw in your head the picture of the left hand climbing to box 1 on the last beat of the comp. Draw the spot the hand will move to in advance, and the timing won't wobble at the moment of the switch.
20–40 min · Real practice: comp→solo switch (BPM 80) Today's goal, the comp→solo switch. Bar 1 throws the question with the A7 boogie; bar 2 answers with a box 1 lick. On the last beat of the comp, raise the left hand to box 1 and connect smoothly into the first solo note.
▶ BPM 80, shuffle. Bar 1 is comp (question), bar 2 is solo (answer). On the last beat of the comp, raise the left hand to box 1 and connect into the first solo note.
When comping and solo connect on one flow, half of your one-person blues is already done.
40–50 min · Recording No A7 backing is fine. Record the switch of comping one bar and moving into a solo bar, and listen for whether the seam is smooth.
Today's completion criteria: You switched smoothly from one comp bar into one solo bar without losing the beat, and recorded the comp→solo switch.
Common mistakes in the switch. Most come from stopping the groove as you move into the solo.
▶ Don't stop the groove. If silence opens up between comping and solo, the conversation breaks.
- Not counting the beat as you move to the solo. Your foot must keep tapping the shuffle. If the groove stops, the switch shows.
- Moving the left hand too far. The comping home and box 1 are a few frets apart. Move the minimum.
- Late because you press the first solo note hard. The first note is timing, not force. Land it right on the beat.
- Raising the speed first. A smooth switch at BPM 80 comes first. Tempo is a later matter.
