Italian lute, now popular with celtic musicians. Originally bowl backed, now often has a flat back like a cittern and 8 strings.
The Mandola (the big brother of the Mandolin), has 8 strings in 4 pairs, tuned in 5ths. The Mandola retains the high-tension stringing but allows lower parts to be played. The Tenor Mandola (or Mandola) is tuned as a Viola, CGDA, one fifth below a mandolin. Octave Mandolas (also known as Octave Mandolins in America) are popular because of their suitability for Acoustic and Celtic music, being tuned GDAE, an octave below a Mandolin. Because the Octave Mandola neck is shorter than a Bouzouki it is easier to finger, but the strings are heavier.
Definition: Large mandola tuned CGDA one octave below normal.
Introduction: Mandocello and Mandobass
The Mandocello is tuned CGDA one octave below the Mandola (however most of them will stand being tuned in GDAE like a bouzouki, using lighter strings). The Mando Bass is a rare beast, but the examples we have had have been tuned the same as a String Bass EADG
