Piano students struggle to develop proper left-hand technique and lack structured guidance on asymmetrical arm weight application

Piano learners, particularly intermediate students, are confused about whether classical arm weight techniques apply equally to both hands, leading to technical plateaus and inefficient practice. Current music education resources treat left and right hand technique as interchangeable without addressing the specific biomechanical and musical demands of each hand, forcing students to piece together fragmented advice from multiple sources or pay for expensive private lessons.
