What is guitar finger numbering?

Guitar finger numbering is a system used to identify and coordinate the fingers of the left hand while playing the guitar. In this system, the fingers are assigned a number as follows:

1. The index finger is numbered 1.
2. The middle finger is numbered 2.
3. The ring finger is numbered 3.
4. The little finger is numbered 4.

This numbering system is used to indicate which finger to use when playing a specific note or chord. For example, a guitar tab or notation may indicate that the first fret of the B string should be played with the index finger, which would be represented by a "1" above the note.

It is important to note that this numbering system is primarily used for the left hand, as the right hand is typically responsible for plucking or strumming the strings. While there may be instances where the right hand fingers are numbered, these are less common in standard guitar notation.
