This notation is often used as an alternative to "standard Western" notation for stringed instrument players who wish to complement learning their music by ear, or who do not "read music".
The standard elements of Tablature notation are that each line represents a string, and the finger-placing/fret is shown. Representation of key, timing, tempo, phrasing, and technique is not standardized.
Sites for publishers of Tablature should be offered to Business/Publishing_and_Printing/Publishing/Music/.
Sites with a more general focus belong in a more general category.
