This book is an introduction to slide techniques for fingerstyle ukulele players. These techniques, suitable for acoustic blues and other musical genres, will stimulate the reader's creativity. It is a practical method thought for expert musicians, who already know some standard fingerstyle and fingerpicking techniques. In Chapter 1 we will start with some exercises for basic slide techinques, then we'll learn to play the melodies of two songs in standard tuning (G - C - E - A). In Chapter 2 We will focus on fingerstyle arrangements and original compositions played with slide techniques in open tunings with Low G fourth string. First I introduce the Open G and Open Am tunings, then we'll approach the study of a blues in G with ground bass thumb technique and three other songs with alternate bass technique. The AUDIO FILES of all the exercises and songs are available following a link inside the book.
