The fretboard for a mandolin player Week 3

Turn Five Shapes into One Connected Map

Seven days on the five major pentatonic windows in C, spent almost entirely at the joints between them rather than inside them.

One day at a time. Do today's card, then close the page.

This week is paper. Nothing on it listens. The lessons, and the checks on your playing, are in the app.

The five pentatonic shapes in C

Big idea: five shapes are one road with four joints and an octave at the end of it.

C major and A minor are the same five notes, which is why this week names both. The reference key is C because that is what the five-shape sheets are drawn in. Almost every minute of the week is spent where two shapes meet, because that is where players stop: the interiors take care of themselves once the joints do.

What this week is for

Four joints, four days, then the outer connection where Shape 5 hands back to Shape 1 an octave up. Saturday runs the whole road once. Sunday records it.

Focus
Reference key, C major and A minor, matching the five shape diagrams. Study the joints more than the interiors.
Exit standard
Travel Shapes 1 to 5 and 5 to 1 without pausing and without looking at the page.

Seven cards on paper, with room to write. Your ticks and your answers come out with it.

The first two joints

Monday + Tuesday

Day 15 about 25 minutes

Joint 1 to 2

Focus: find the crossing points between the first two shapes and use all of them.

1 2 3 4 5 6 7 8 9 10 G D A E 6 1 3 5 1 2 5 6 2 6 3 1
Shape 1 in ink and Shape 2 in green, C major pentatonic, which is also A minor pentatonic. Numbers are scale degrees of C and the orange dots are C. The three gray dots belong to both shapes: those are the crossing points the day counts. The C on the G course is in both as well, and it stays orange, because orange means the root on every board in this workbook.
1 2 3 4 5 6 7 8 9 10 G D A E 6 1 3 5 6 2 3 6 Shape 1 Shape 2
One loop, Shape 1 into Shape 2. Follow the arrows. The number in each dot is the scale degree. Ink is Shape 1 and green is Shape 2, the same colors as the board above. Play A, C and E in Shape 1. The circled G is in both shapes: it is your fourth note in Shape 1, and the hand moves into Shape 2 on it, so it is drawn green. Then four notes in Shape 2: A, D, E and A. The way back is the same notes in reverse. Every day this week, and Weeks 4 and 8, repeat this loop where other shapes meet. It is drawn here once to show the move.

Why the same five notes have two names: C, D, E, G and A are the C major pentatonic and the A minor pentatonic at once. Nothing about the notes changes, only which one you treat as home: the orange dots on the board are C and the dots marked 6 are A. Stop on C and it sounds like C major, stop on A and it sounds like A minor. That is the whole difference, and Week 4 spends two days on it.

Day 16 about 25 minutes

Joint 2 to 3

Focus: cross the second joint without the pulse noticing.

1 2 3 4 5 6 7 8 9 10 11 12 G D A E 1 2 5 6 2 3 6 1 3 1 5 2
Shape 2 in ink and Shape 3 in green, C major pentatonic. Numbers are scale degrees of C, the orange dots are C, and the gray dots are in both shapes. So is the C high on the E course, still orange. Visualize the whole overlap before you play.

What question and answer means: Two phrases that belong together. The first leaves something open, usually by stopping on a note that is not the root, and the second closes it in the same rhythm, usually by arriving on one. Playing the question out of one shape and the answer out of another is what turns a position change into a musical event rather than a piece of hand management.

The last two joints

Wednesday + Thursday

Day 17 about 25 minutes

Joint 3 to 4

Focus: make the third joint as available going down as going up.

5 6 7 8 9 10 11 12 13 14 fret G D A E 2 3 6 1 3 5 1 2 5 2 6 3
Shape 3 in ink and Shape 4 in green, C major pentatonic. Numbers are scale degrees of C: the orange dots are C, the tonic, and the dots marked 6 are A, the relative minor's root. The gray dots are in both shapes, and so is the C on the D course, still orange.

Day 18 about 25 minutes

Joint 4 to 5

Focus: vary which finger starts the shift, so the crossing is not one memorized move.

7 8 9 10 11 12 13 14 15 16 17 fret G D A E 3 5 1 2 5 6 2 3 6 3 1 5
Shape 4 in ink and Shape 5 in green, C major pentatonic, up where the neck runs out. Numbers are scale degrees of C, the orange dots are C, and the gray dots are in both shapes.

Up where the neck runs out: These two shapes sit at and above the twelfth fret, where the frets are narrow, the notes are quieter and every crossing looks the same. Two things help: leave the thumb where it was rather than climbing with the whole hand, and pick a little nearer the bridge so the notes keep some body. If the intonation goes here, it is usually the left hand squeezing rather than the shape being wrong.

The octave, then the whole road

Friday + Saturday

Day 19 about 25 minutes

Outer connection

Focus: stop treating the top of Shape 5 as the end of the road.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 G D A E 5 6 2 3 6 1 3 5 6 1 3 5 1 2 5 6
Shape 5 in ink and Shape 1 in green, C major pentatonic, on one neck. Numbers are scale degrees of C and the orange dots are C. No gray dots here, because these two share no fret. The octave joins them, and that is the repeated register the first step sends you looking for.

What the outer connection is: The five shapes are a cycle rather than a ladder: after Shape 5 comes Shape 1 again, an octave higher. On a mandolin neck that octave does not exist, so the top of Shape 5 hands back to the bottom of Shape 1 as a change of register instead. A player who does not know this treats the top of the neck as a dead end and turns round there every time, which is audible.

Day 20 about 25 minutes

Full chain

Focus: run the whole road once, then repair only what broke.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 G D A E 5 6 1 2 3 5 6 2 3 5 6 1 2 3 6 1 2 3 5 6 1 3 5 6 1 2 3 5 Shape 1 Shape 2 Shape 3 Shape 4 Shape 5
Every note of the C major pentatonic to the fifteenth fret, with all five windows bracketed underneath. Numbers are scale degrees of C and the orange dots are C. The brackets overlap because the shapes do. That overlap is the road.

The phase check

Sunday

Day 21 about 25 minutes

Phase check

Focus: record the round trip and hear whether it is a scale or a line.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 G D A E G A C D E G A D E G A C D E A C D E G A C E G A C D E G Shape 1 Shape 2 Shape 3 Shape 4 Shape 5
The same chain in note names instead of degrees, since naming is part of what the test checks: C major pentatonic to the fifteenth fret, the orange dots are C, and the five windows are bracketed underneath.

Sunday checkpoint

  1. Can I travel Shapes 1 to 5 without pausing?
  2. Can I travel 5 to 1 the same way?
  3. Did I do both without looking at the page?
  4. Did it pass on two attempts at least ten minutes apart?

Advance when the exit standard passes twice, the two attempts at least ten minutes apart. If it did not, repeat only the days that failed rather than the whole week.

Week 3 success looks like

  • Every joint has more than one crossing note available.
  • The round trip runs once through with the pulse intact.
  • Shape 5 leads somewhere instead of stopping.

Questions and discoveries

Keep the pace: the seven week route is decided here. Take this week's exit test in two keys, and if both pass, Week 4 can be folded into the warm-ups of Weeks 5 to 7 instead of taken whole.
