“A violinist, a lyric soprano doggo, and an unexpectedly somber piece of music. Nikolas the Border Collie has been doing the rounds on social media, thanks to his wonderfully lyrical, operatic howls,” writes Sian Moore in Wednesday’s (8/11) Classic FM. “As the pooch’s wistful warbling echoed across the Internet, the Dallas Symphony Orchestra saw the potential for a duet. Cue their co-concert master, Nathan Olsen, and his violin. Using the TikTok ‘duet’ feature, Olsen accompanied the four-legged vocalist’s haunting howls with a melancholic violin solo to match. And so, the ‘doggo’s lament’ was born…. It’s only a short performance, but it’s one loaded with sorrow and turmoil, so much of which hangs on that woeful semitone drop…. As the duet comes to an end, the Dallas Symphony Orchestra adds the on-screen caption: ‘What instruments are missing from this ensemble?’ Other musicians have answered the question, through a variety of collaborations with the operatic hound. Musician and TikTok user Amosdoll Music provided a livelier soundtrack to the dog’s howls on his piano. And producer and composer Raziel added some powerful orchestration to the canine’s crooning, which he shared on TikTok with the caption, ‘Dog Sonata F# Minor.’ ”
