Laúd
Laúd (Spanish: "lute") is a plectrum-plucked chordophone from Spain, played also in diaspora countries such as Cuba and the Philippines.
The laúd belongs to the cittern family of instruments.  The Spanish and Cuban instruments have six double courses in unison (i.e. twelve strings in pairs); the Philippine instrument has 14 strings with some courses singled or tripled.  A similar, but smaller instrument, with a shorter neck, is the bandurria, which also exists in 12- and 14-string versions.Traditionally the laúd is used by folk string musical groups, such as Spanish or Filipino rondalla string ensembles, together with the guitar and the bandurria. Like the bandurria, it is tuned in fourths, but its range is one octave lower.

Tuning
For the Spanish laud the tuning is:

1st: A4 A4
2nd: E4 E4
3rd: B3 B3
4th: F#3 F#3
5th: C#3 C#3
6th: G#2 G#2The Cuban tuning is:

4th: E3 E3
5th: A2 A2

2nd: D4 D4 D4
3rd: A3 A3 A3
4th: E3 E3
5th: B2 B2
6th: F#2Steve Howe plays a laúd in both Yes (band) and as a solo artist, but he incorrectly refers to it in his guitar book as a Portuguese guitar. His tuning is:

1st: A-flat E
2nd: B E
3rd: B E
4th: A-flat A-flat
5th: E E
6th: B B

Cuban laúd
There is also a Cuban variety of laud—called the "Cuban laud" -- (such as played by Barbarito Torres of the Buena Vista Social Club). It has the same appearance and use as the Spanish version, six sets of doubled strings, but a shorter scale length and higher tuning.  Sometimes the Cuban variety has a different body shape, with two points instead of the lute-style or wavy shapes used for the traditional Spanish variety.  The tuning is:

1st: D5 D5
2nd: A4 A4
3rd: E4 E4
4th: B3 B3
5th: F#3 F#3
6th: D3 D3
