Between 1953 and 1967, the Italian composer Mario Castelnuovo-Tedesco wrote a series of Greeting Cards. These 52 musical folios, 21 of which were written for the guitar ﾖ an instrument that had inspired him since he first heard Segovia perform ﾖ are pen portraits of admired colleagues. Castelnuovo-Tedescoﾒs imagination and technical mastery are reinforced by the use of rhythms associated with the dedicateesﾒ nationality or through evocations inspired by their names. The cycle offers a surprising, generous and rewarding body of musical cryptology that belies its small scale form.
