A friend of mine is considering publishing a number of his songs transcribed for tablature. I received a pdf file and will spend some time evaluating the accuracy and ease of reading what has been produced for him prior to publication or posting on the internet.
Now, I don't want to be snooty, but I noticed a few things up front that I'll ask questions about. The first is that the notation at the top of the tab is the melody line from the vocals of the song. Now, as a player, I'm looking for the actual notes being played on the guitar, not the notes to the vocals. I know how the vocals go, I have the cd. One of the things that you can do with tab notation at the top is to show which fingers are playing which notes so as not to confuse the player with the numbers that represent the number of the fret you're playing on a specific string. It separates them out. So, if I am playing the 1st E string at the second fret, the tab will show it on the fretboard as a 2 on the first string. But what finger I'm using is also represented by a number. If I play with my index finger (1), I can't put that number next to the fret number in the tab it is too confusing. I'd have a one and two next to each other. The notation at the top allows me to put the finger number there for a reference. This helps in the player's preparation for the next move and chord configuration. This is especially helpful in difficult pieces where you want to anticipate and prepare for easy transitions from chord to chord, note to note.
The next thing that was absent from the tab I was sent were ties that show slides or hammers or pulloffs. Now I know my friend has them when he plays, but they are not represented in the tab itself. It is incomplete for the player who wants to reproduce the nuance of the original.
A third, and an even more picky point, is that the chord diagrams are included in the middle of the staff, above the tab and below the melodic notation. This gives a cluttered effect. It is awfully tight. Look for tab that shows only the chord names. You can figure the fingering from the information provided in the tab.
When you're getting ready to buy tab off the internet, or see it in a book or magazine, these are things you can look for at the outset, before you even try to play it. It will save some frustration.
Now I have to go play what's written and see if it gets it right. There might be more in another article.
