Did any of the 16th, 17th, 18th, or even 19th century master luthiers make fractionals that would today be considered masterpieces ~ just smaller? I've not seen references to named famous instruments played by children, like the ex-Young Midori or the ex-Young Sarah Chang or the ex-Young Yo-Yo Ma. Did they simply have to wrestle with full-sized instruments when performing with major orchestras? Thanks.
