Frets names

A fret name is given by a string name and a fret number. The string name is one of E, A, D, G or B.
The fret number is a number from 0 through 23.
Examples of valid frets names are: E0, E23, A12, G1, B3 etc. .
While entering frets names, separeate them with commas e.g. E0,E23,A12,G1,B3.

Tab to scales search

Enter up to 30 lines of a tab to discover what scale a piece of music represented by it is in.


This tool considers tab lines, which start with a string name E,A,D,G,B or e followed by |, and end with |, only.
Hence, a valid tab line looks similar to the one below (important bits marked in orange):


Everything else, including empty, or not well-formated lines, gets ignored.
