However it is not absolutely necessary - you learn as you go on. This is essential if you are going to be any good. And you must practice - it is essential to make progress. The Vellum needs to be tight, the bridge is set in the correct position i.e. twice the distance of the twelfth fret from the nut, there are some decent nylon strings fitted, the arm angle and position must be set correctly to give the correct height of strings above the Vellum and the instrument must be in tune. Tuning the Instrument Buy a set of tuning pipes and simply tune the strings accordingly or check using a piano, keyboard or even another uke- but get it in tune.
Chords Now is the time to start playing.
Look at the diagrams below. But if you ve never done this before, those fingers will seem like sausages and they just will not go where you want them to go - and even if they seem to be in the right place, it just doesn t sound right. Make sure that you are pressing the strings firmly just behind the frets. Not on the fret or you will just get a dull thud instead of a bright note. You need to practice these three chords over and over again, changing positions from one chord to another so that it becomes an automatic process.
