Whatever we dwell upon has its "tuning" effect upon our thoughts, and thus we reach some of the lore and wisdom of those who have trodden the way before us. The inventor and the discoverer are truly what the words imply: the inventor "comes upon" the new idea or principle, and the discoverer "uncovers" and makes plain. But all the ideas and all the new and novel discoveries, and all the laws, were there before: we only reach them when we have climbed to a sufficient height to be able to apprehend them. So the musician who reaches the spirit of Bach has, by the attunement of his thoughts and his aspirations, crept into the heart of the music and has tugged at the musician's heart-strings. He has touched the composer's soul, and henceforth he plays Music, not notes. Again, Bach, and all the masters of Music have in their turn but discovered the Music that was already there. No man really creates, any more than the gardener creates an oak tree by the planting of an acorn. The gardener provides the necessary conditions in which the oak, already miraculously pent within the acorn, can unfold and develop. So the musician also provides the necessary conditions in which the spirit of Music can blossom and bear fruit. He need take to himself no vast amount of credit, for he is but a trustee of that which has been lent to him: he neither creates it nor owns it. His music is a gift of spirit, and when by his life's work he has glorified that gift, then henceforth that is his contribution to the universal store of spirit, and his Art belongs to the ages.
