> *The Educational Benefits*

>
> 1. *Simplifying Tablature for Beginners*:
>
> When beginners are learning guitar, especially for accompaniment, they
> often only need to focus on the chord shapes for the left hand and the
> plucking patterns for the right hand. Displaying *right-hand fingerings (p,
> i , m, a)* directly on the tablature, instead of fret numbers, would allow

>
> In typical guitar accompaniment, the player is usually following a set
> plucking pattern while holding down chord shapes. Showing fret numbers on
> the tablature in this context can be redundant, as it provides no
> additional value. Instead, showing the right-hand fingerings (e.g., p for
> thumb, i for index, m for middle, a for ring finger) would make the
> tablature clearer and more directly useful.

> 3. *Focusing on Key Learning Aspects*:
>
> By replacing fret numbers with right-hand fingerings, students can better
> understand the relationship between the root notes of the chords and which
> fingers to use. This helps them develop a more intuitive understanding of
> how to accompany songs, particularly when learning fingerstyle or arpeggio
> patterns.

>
>
> • The chord shapes for the left hand.
>
> • The plucking pattern for the right hand (using P, I, M, A).

> • The importance of plucking the correct string for playing the root notes
> with the thumb (p).
>
>
> In most existing tablature systems, the students are presented with fret
> numbers, which are not necessary for accompaniment-focused learning. If
> instead, the tablature showed p, i, m, and a for the right-hand fingers,
> the students could more efficiently learn which fingers to use on which
> strings, while ignoring unnecessary fret number information.
