Marovany
The marovany is a suitcase shaped, wooden, type of box zither from Madagascar, used in Malagasy music. It is strung on both sides with metal strings. The player plucks the strings with both hands, often with rapid alternation. This often creates complex rhythmic patterns, typical of Malagasy music. It is tuned in sequences of thirds.The instrument is commonly used in rituals and spiritual gatherings.
