      "full_description": "Some violins simply work cleanly. Others make music feel alive.   The Violin 22151 by Holger Krupke clearly belongs to the second category.   This handcrafted master violin develops a tone full of warmth, clarity and expression. From the very first notes, it reveals an open response and a remarkable balance between precision and musical depth.  The sound remains clear and projecting without ever becoming harsh or aggressive. That balance is exactly what makes premium violins so special: controlled yet emotionally open.   This violin doesn\u2019t only react to technique. It reacts to personality.   The traditional handcrafted construction creates a direct connection between player and instrument. Subtle dynamics become instantly audible, while stronger bow pressure develops impressive tonal richness and projection.  Especially in the middle and upper registers, the Violin 22151 develops a singing and lively tonal color full of character. That makes it equally suitable for solo, ensemble and orchestral performance.  For advanced players. For ambitious musicians. For people who don\u2019t just want to play music correctly. But tell stories with it.   Not sterile. Full of expression.   Handcrafted by Holger Krupke. Traditional German master workshop craftsmanship.",
      "additional_text": "Handcrafted master violin by Holger Krupke \n Warm, clear and projecting tonal character \n Highly responsive feel with wide dynamics \n Lively and open tonal development \n Traditional handcrafted construction \n Suitable for solo, ensemble and orchestral performance \n Balanced response across all registers \n Designed for advanced and ambitious musicians \n Traditional craftsmanship \n Made in Germany",
