"It sounds hoarse, doesn't it?" I asked my cello teacher the other day. "Yes," she said. I shifted my Czech made instrument and ran the bow along the D string. It gave off a muted, unclear note. "I don't know why," I said. "I wonder if it's the bow." "Did you put plenty of rosin on?" "Yes, before I came out." "It's not the bow," she said, decisively. "It's your cello. It just changed its tone with the weather. They all do that." "They all do?" "Yes," she said. "It can be a terrible nuisance for a soloist." "That's not a problem that's ever going to bother me," I thought, remembering how well her pupils of ten and twelve years old played when compared with me. We went on with the lesson. For those of us who are in love with this beautiful, resonant instrument it is not difficult to give character, personality and a life to it. So, sometimes I do. And it is as clear as could be (in my opinion) that as my cello varies its tone with the weather, because the materials from which it is made are responsive to their environment, so do I...and you and those you love. That's what MediClim is all about.
