      "full_description": "Some instruments simply work.\u00a0 Others instantly make you feel something.\u00a0   The Violin\u00a022101 by Norbert Knappe clearly belongs to the second category.   At first glance, it\u2019s obvious this is not anonymous factory production. The hand-applied varnish, elegant arching and carefully selected tonewoods don\u2019t feel sterile or overpolished.  They feel alive.  And that\u2019s exactly how this violin sounds.  Warm in tone. Open in response. Powerful enough for stage and ensemble playing, yet sensitive enough for quiet musical moments that don\u2019t need volume to leave an impact.   This violin doesn\u2019t only react to technique. It reacts to personality.   The longer you play it, the more the instrument opens up. Notes develop character. Melodies gain tension. And suddenly you realize you\u2019re no longer just practicing \u2014 you\u2019re actually making music. That\u2019s exactly why handcrafted violins feel different from industrial instruments. Small details in the wood, varnish and construction give every instrument its own unique voice. Perfect for students, ambitious players and musicians searching for an instrument that will stay with them for years instead of just surviving the first lessons. Classical music, film scores, folk or modern pieces \u2014 the\u00a022101 feels at home wherever music is meant to sound honest instead of perfect.   Sounds better when you make it yourself.   Crafted by Norbert Knappe. For people who don\u2019t just want to consume music. But truly feel it.",
      "additional_text": "Handcrafted violin by Norbert Knappe \n Warm and open tonal character \n Responsive feel with excellent dynamics \n Premium tonewoods and traditional construction \n Hand-applied varnish \n Suitable for students and ambitious players \n Perfect for classical, folk, film music and modern styles \n Traditional violin craftsmanship \n Made in Germany",
