Tablature is a form of musical notation, which tells players where to place their fingers on a particular instrument rather than which pitches to play. Power Tabs takes it a step further to add audio tracks and scrolling music to the tab. This is why Power Tabs is by far the easiest tablature to use.
Tablature is mostly (but not exclusively) seen for fretted stringed instruments, in which context it is usually called tab for short. It is frequently used for the guitar, bass, lute, archlute, theorbo, angélique, mandora, gallichon, and vihuela, but in principle it can be used for any fretted instrument, including ukulele, mandolin, banjo, and viola da gamba, as well as many free reed aerophones such as the harmonica.
While today tablature is commonly used in notating rock and pop music, it is often seen in folk music, and was in fact common during Renaissance and Baroque eras. (In the context of guitar tab, standard musical notation is usually called 'staff notation' — even though tab is also written on a staff — or just 'notation'). An alternate (some would say incorrect) usage of the word "tab" or "tabs" is common on the internet, where they refer to conventional chord symbols (for harmony), or note names (for melody).
Now that we've established exactly what a "tab" is, what can it do for you, the normal, everyday guitar or bass player?
If you need to learn a song, a power tab will shorten the time required to learn the chords, lead, bass lines, etc.. You can also play
