Dear Karen, I have used a tapered 5/8" dowel with a piece of hammer felt glued to each end. I hold the stick in the middle and hit the keys with either end. Works great, but use ear plugs when you tune this way or you WILL damage your hearing. You can shape the dowel to fit you hand with duct tape or some such until it feels just right for your hand. There was along thread on this subject three years or so ago most likely under the title of test blows. Newton
