Tenor ukulele sizes were introduced in the 1920s to meet players' demands for bigger, fuller-sounding Ukulele.
Concert and tenor Ukulele are relatively close in size, tone, and playability, so for the sake of this article I'm lumping them together.
Tenor Vs. Soprano
Tenor Ukulele are noticeably different than a soprano when it comes to playability and tone.
Tenor ukuleles have a longer scale than a soprano: 17" for the tenor.
The longer scales creates more room between the frets. As a result, many people find concert and tenor Ukulele's more comfortable to play than sopranos.
Tenor ukuleles also tend to sound bigger and fuller than an equivalent soprano sized Ukulele's. In general, Tenor size Ukulele's will have more bass, resonance, sustain, and volume.
Most players feel that the robust tone of a tenor Ukulele makes them a bit more versatile than sopranos.
