The natives called it Ukulele, meaning jumping flea, and this curious name was picked up by the American inhabitants and Europeans, and it was as Ukulele that this little instrument found popularity with first the Americans and then the British, whereas as Machete, it had been a purely national folk instrument of the Portuguese.“

For you can produce sounds very easily and accompany solo singing or popular songs or melodies. If mastered well, you can also play solo melodies, but as this instrument developed as an accompanying instrument, it is better suited [for accompaniment].“

If a popular melody is spontaneously on your tongue every day, then the ukulele is really a practical tool to accompany you carefree. As one progresses, it is not difficult to play a solo with the ukulele. Anyway, it does not take too much effort to acquire the beautiful sounds that this instrument produces. The ukulele was originally a Hawaiian instrument but has recently become extremely popular throughout America …“ (p. 1)
