The audio begins with the soft yet distinct sound of a viola. A technique known as glissando is employed, where the pitch smoothly ascends and then descends, creating a sweeping effect. It's as if the viola is transforming its sound right before your ears, shifting from one note to another seamlessly. The entire experience lasts a brief but memorable ten seconds, leaving a resonating echo of the viola's unique tone. The glissando technique truly highlights the viola's versatility and expressive range, creating a captivating and dynamic listening experience.
