The last example is a Jazz phrase over a II/V/I chord progression in the key of Db Major. It begins to tie together the concepts of rhythm and notation reading. I've intentionally put it in a key with five flats to add an extra challenge to your reading. Its extremely beneficial to have the ability to sight read in every key. Note the accidental at the end of the phrase which resolves chromatically from A natural to Ab.
Although the TAB is included below the notation, it is best if you concentrate on reading the notation for the purpose of learning to sight read. If you can't figure out which position a particular note should be played in, the TAB will allow you a quick reference.
