The ukulele has risen to become the fastest growing musical instrument for a reason. It sounds just beautiful and it’s so easy to play. Many chords may be played with one or two fingers. It is the first instrument for many artists and always an arms length away for others. Ukuleles commonly come in four sizes: soprano, concert, tenor, and baritone. A maker we like is Kala Stays in tune, good intonation.
There a many good apps for Iphone and other mobile devices for tuning any instrument.
