      "full_description": "The best instruments don\u2019t try to sound perfect. They sound real.   The Viola 22132 by Norbert Knappe does exactly that.   Warm, dark and full of character, it creates a tone that doesn\u2019t simply disappear after each note. Every sound carries weight. Every movement of the bow changes the color and emotion of the instrument. That\u2019s exactly where the difference between an instrument and a musical companion begins.  The handcrafted construction and carefully selected tonewoods create an exceptionally open response and impressive dynamics. Soft passages remain smooth and controlled, while stronger bow pressure develops remarkable depth and projection.   The Viola 22132 doesn\u2019t only react to technique. It reacts to personality.   With violas especially, the subtle details in tone often decide whether music truly moves people or simply sounds correct. That\u2019s why this instrument feels so alive. It creates warmth, tension and expression instead of sterile precision. Chamber music, ensembles, film scores or modern arrangements \u2014 the Viola 22132 stays flexible while maintaining a strong identity of its own.  For advanced players. For ambitious musicians. For people who don\u2019t just want to hear sound. But feel it.   Not perfect. But yours.   Handcrafted by Norbert Knappe. Traditional violin-making craftsmanship from Germany.",
      "additional_text": "Handcrafted master viola by Norbert Knappe \n Warm, dark and projecting tonal character \n Highly responsive feel with wide dynamics \n Traditional construction using premium tonewoods \n Hand-applied varnish \n Suitable for ensemble and solo performance \n Perfect for classical, chamber and modern music \n Designed for advanced and ambitious players \n Traditional craftsmanship \n Made in Germany",
