Summary
This quote implies that music itself is vast and limitless, akin to an ocean. However, the repertory (body of musical compositions and pieces) is much smaller and limited, more like a pond in comparison. It suggests that although there are countless possibilities and potential for creativity within the realm of music, the actual selection of widely-known or frequently performed works is relatively small in comparison. This quote highlights the vastness and depth of music as an art form, while also revealing the need for exploration and expansion within its repertoire.
