I'm learning without a teacher so I'm asking my friends at this site to help define a term I'm not familiar with. I'm a beginning classical guitarist and am learning pieces from the "Fifty Easy Classical Guitar Solos" book by Jerry Willard. I've learned six thus far but something foxes me regarding the last one. It's the next to the last solo in the book, pp 76 (track number 50 on the accompanying CD): "Estudio" by Francisco Tarrega. This beautiful, somber, piece has two parts, A&B. The A part repeats then you go into the B part and finish by repeating that as well. The first line of part B, the second measure, has a notation above the notes. It looks like this: CV---------------------------------| (only the dashes are a straight line). The letters CV are above the first notes (a pinch) in this measure and the "bracket" extends all the way to the end of the measure. What does CV mean? The book does not explain. I don't know if it matters, but this piece is in 3/4 time. This is the only place this notation appears on this piece; could it mean "constant volume?" Thanks in advance!
