Section 1 • P-i-m-a Notation

1. Natural Finger Assignment (PIMA)

P6th, 5th & 4th Strings (Bass)

Thumb

Handles low bass notes and continuous bassline motion.

i3rd String (G)

Index

Melodic support in the middle register.

m2nd String (B)

Middle

Intermediate voice and central arpeggio notes.

a1st String (High E)

Ring

Leading melody and treble notes.

Listen: p, i, m, a over C

First the bass with the thumb, then the treble strings one by one. Count the notes as they sound.

Listen to the difference between striking all strings together or playing them individually, comparing versus . In the arpeggio, each note has its moment, and it's clearly perceived if one finger plucks harder than another.

2. Essential Arpeggio Patterns

From the lowest to the highest string.

beginner3/4

Anonymous Romance (Ascending-Descending)

P - i - m - a - m - i

The classic fundamental Spanish repertoire pattern (P - i - m - a - m - i). Great for ring finger mobility.

Try with Em, Am, B7, E

Pop Ballad Arpeggio (P - i - m - a)

P - i - m - a - i - m - i - m

Smooth 8-eighth-note arpeggio (P - i - m - a - i - m - i - m) widely used in acoustic pop ballads.

Try with C, Am, F, G

intermediate4/4

Giuliani Study No. 1 (Op. 1)

P - i - m - a - P - i - m - a

Finger independence exercise designed by Italian virtuoso Mauro Giuliani in Vienna.

Try with C -> G7 -> C

advanced6/8

Cross Arpeggio (Folk Fingerpicking)

P6 - i - P4 - m - i - a

Alternating bass pattern emulating acoustic folk and blues Travis picking.

Try with G, C, D

Section 4 • Technical Tips

3. Tone & Fluency Keys

Rest Stroke vs Free Stroke

Use free stroke (tirando) for continuous arpeggios and rest stroke (apoyando) to highlight lead melodies.

Metronome Sync

Practice at a slow tempo (60 BPM) ensuring even volume and pulse across all fingers before speeding up.

Thumb Independence

Position your thumb slightly ahead of the fingers to prevent collisions during fast fingerpicking.

Listen to an arpeggiated progression

The same classic progression with C, Am, F, and G, note by note. Make sure no note covers the others to achieve a clean sound.

5. Cross-rhythms in arpeggio practice

A polyrhythm places two pulse groupings within the same duration.

In the three against two pattern, the span is divided into six equal parts. The first layer plays on parts one, three, and five. The second layer plucks on parts one and four. The first attack coincides in both voices. The subsequent notes alternate. Count the subdivisions regularly before changing chords.

Subdivision	Three-part layer	Two-part layer
1	×	×
2	—	—
3	×	—
4	—	×
5	×	—
6	—	—

On the guitar, the thumb can mark a regular binary bass. Meanwhile, the treble fingers play a ternary figure.

It's advisable to practice each layer separately. Then combine them at a slow tempo. Only increase the speed if the pulse remains even. Your hand should stay relaxed at all times. This method also works for four against three using twelve shared parts.

Four against three

For four against three, count twelve equal subdivisions. The layer of four attacks enters every three parts on one, four, seven, and ten.

The layer of three attacks enters every four parts on one, five, and nine. Play one layer as a soft pulse in the bass. Play the other on a treble string. This way, you'll hear the exact point where both layers coincide again.

6. A weekly arpeggio routine

Arpeggio technique progresses with brief, regular sessions. Dedicate each day to a single technical goal.

Divide the week into three clear phases. In the first phase, play a single pattern with your thumb, index, middle, and ring fingers over an open chord. Monitor the metric regularity of each note.

In the second phase, keep the pattern but change chords in each measure. Prepare your fingers before the change. In the third phase, choose a chord progression and play it fluidly.

Use the metronome as a guide for metric regularity. Don't use it as a speed race. Start at a tempo where you can achieve four clean repetitions. Then gradually increase the pulse. Keep your muscles relaxed.

Record yourself once a week to detect uneven notes. Finally, alternate rest stroke and free stroke in the upper voice. This will make the melody stand out clearly.

7. Check yourself

Short questions to reinforce what you've just read. There's no grade or record, so if you miss one, just listen again and repeat.

Which finger plays the three lowest strings?

Listen to both. Which one is an arpeggio?

In an arpeggio, which stroke lets every note keep ringing?

Try it on your guitar

Hold a C chord. Play the thumb on string 5, then i on string 3, m on string 2 and a on string 1. Count «1, 2, 3, 4» out loud, one note per number, eight times in a row without speeding up.

Once it sounds even, do the same with Am, F and G, like the progression you just heard.
