 The official statement from Narciso Yepes and the Yepes heirs is that Narciso Yepes, being a young boy, originally composed the piece for his mother when he was about seven years old (c.1934) and soon thereafter performed it between acts at the Teatro Guerra, in Lorca, Spain.Some time later, he recounts, when he was thirteen years old he attended a performance in Valencia and heard his composition performed by another guitarist, who indicated the authorship as "anonymous".Yepes contends that the melody had been plagiarized (with some changes to the arrangement) by someone who, he assumes, must have attended that first performance.
