The Jupiter 507RSO is labeled a student instrument, but it is aimed at the motivated student, in that it possesses features that appear on professional instruments, notably open hole keys. The sooner a student can begin to develop a sensitivity to pitch, the better his or her ear becomes. This is a beautiful looking, mechanically reliable and musically satisfying instrument that is built to withstand the rigors of student ownership. It is well-made, sounds fantastic and should provide many years of use.
