Cora Gordon wrote, "Jan had conceived a passion for the Spanish guitar during the war and was determined to sample the music of this instrument at source .." and visit Spain they then did. Their first journey (in 1920, often mistakenly stated to be 1921) is described in "Poor Folk in Spain" (1922) and the second in "Misadventures with a Donkey" (1924).
One particular musical instrument features in both tales. "I have an old guitar. It is a unique instrument, none other like it has ever been seen in Spain" said the man who sold the guitar to Jan (Poor Folks in Spain, pg. 233). "The guitar was of a strange form and with a scrolled head, the curve of its shape having some of the beauty to be found in negro sculpture" (pg. 238).
On their second journey the Gordons were influenced towards taking a southern route because it would take them through " .. a town named Vera, at which eighty years ago a Don Gomez Fuentes had made a queer guitar which had fallen into my hands." The instrument was actually made by D. Antonio Gimenez of Vera in 1854. It now resides in the Horniman Museum of Forest Hill, London.
During a concert in 2011 (in Muscat, Oman), watching Venezuelan friend Osman playing, I came to realize that the instrument has the pear-shaped body of a bandola central (or mirandina or guariqueña), an instrument still used today in Venezuelan folk music, but long forgotten (or not known) in Spain. Jan's instrument has six strings (and I don't know what the tuning was). Perhaps D. Antonio Gimenez had seen a South American bandola and was inspired to make an instrument with this same pear-shaped form?
