The LU-21A is a pack designed exclusively for Amazon.com! This combines our most popular ukulele with a polyfoam hardcase, and a Lanikai Soprano, Concert and Tenor Ukulele Instructional Booklet. The LU-21 is the best selling Soprano Ukulele offered by Lanikai. With the attention to detail and easy playability it is easy to see why. This handcrafted ukulele is made with Nato wood (otherwise known as Eastern Mahogany) on its top back and sides. When this wood choice is paired with the Rosewood fingerboard it brings out a mellow tone with an enhanced midrange that is often missing in instruments in this price point. With the easy playability, and included instruction booklet written by Mary Lou Dempler you will be playing in a matter of minutes. If you have never played ukulele before get ready for a world of fun. The ukulele is an addicting instrument that can and will be taken everywhere. The standard tuning on a Soprano, Concert, and Tenor ukulele is GCEA, and on a Baritone DGBE. If you can play one ukulele you can play them all!
