So far, there are few studies of string instruments with bows because there aremany parameters to acquire skills and it is difficult to measure theseparameters. Therefore, the aim of this paper is to propose a design of alearning environment for a novice learner to acquire an accurate fingerposition skill. For achieving the aim, we developed a learning environmentwhich can diagnose learner’s finger position and give the learner advice byusing magnetic position sensors. The system shows three windows; a fingerposition window for visualization of finger position, a score window fordiagnosing finger position along the score and command prompt window forshowing states of system and advices. Finally, we evaluated the system by anexperiment. The experimental group improved accuracy values about fingerpositions and also improved accuracy of pitches of sounds compared withcontrol group. These results shows significant differences.
