French Renaissance style lute tablature, with corresponding notation for guitar: a simple Renaissance dance, printed by Pierre Attaingnant.Lute tablature is conceptually similar to guitar tablature, but comes in at least three different varieties. The most common variety used today is based on the French Renaissance system (see example at right). In this style the strings are represented by the lines on the staff (occasionally the spaces above the lines on the staff), and the stops are indicated by lowercase letters of the alphabet (rather than numbers), with the letter 'a' indicating an open string and the 'j' skipped (as it was not originally a separate letter from 'i'). A six-line staff is used, just as for modern guitar tab. However lutes were not limited to 6 strings or courses (they could have as many as 19), and stops for any courses beyond the sixth were shown below the bottom line, with short diagonal strokes (see below).

The letters soon developed somewhat stylized forms for ease of recognition. In particular, the letter 'c' often resembled 'r'. This was common in many styles of Renaissance handwriting, but also helped to differentiate 'c' from 'e'. Also, sometimes 'y' was used for 'i'.

Lute tablature provides flags above the staff to show the rhythms, often only providing a flag when the length of the beat changes, as shown in the example. (Notice that this piece begins with a half measure.)

Other variants of lute tablature use numbers rather than letters, write the stops on the lines rather than in the spaces, or even invert the entire staff so that the lowest notes are on top and the highest are at the bottom.

As with guitar, various different lute tunings may be used, all written using the same tablature method. A tenor viola da gamba can usually be played directly off lute tablature as it typically uses the same tuning. A guitar can often be played off lute tablature by tuning the g string down to an f# and putting a capo at the third fret to preserve the original pitch.
In standard Baroque lute tabulature, each staff has six lines, representing the FIRST six courses. The course of the highest pitch appears at the top, and that of the lowest appears at the bottom. Please note that Italian Archlute of the same period uses an opposite system.

Lower case letters or "glyphs" are placed on each of these lines to represent notes. If you are required to play an open D course, for instance, a small "a" will be placed on the appropriate line. For a note with the finger on the first fret a "b", a note on the second fret a "c", etc. However, as mentioned above, "j" was not used since it was not considered a separate letter from "i", and "c" often looked more like "r". Thus: 

would represent a G-minor chord,
All open strings would represent a D-minor chord:

The strings below the 6th course are notated with additional short "ledger" lines: glyphs are placed below the staff. These courses are tuned in accordance with the key of each piece played:

The rhythm is notated in a fairly straightforward manner: It is represented by headless note-stems with tails [stylized similarly but some regional variations (in spite of some variety the confusion is rare)], with the exception of whole and half notes (semibreves and minims), whereas it would be essential to use heads.
The ornaments would require a special discussion, as many composers used rather personalized sets thereof.
