"Craft an energetic, contemporary electronic track that integrates rare and unique instruments. Incorporate the sounds of the Hang Drum for its melodic and ethereal tones, the Theremin for its electronic and otherworldly vibe, and the Didgeridoo for its deep, resonant undertones. Blend these with light percussions like the Cajón or Djembe to maintain rhythm. The composition should exude innovation and creativity, with an upbeat tempo that's both uplifting and inspiring. The melody should weave these distinct sounds together seamlessly, creating a cohesive yet intriguing auditory experience. The track should be approximately 15-20 seconds, culminating in a gentle fade-out, setting the stage for dynamic conversations. The overall feel should be fresh, unique, and energetic, encapsulating the innovative spirit of modern creative discussions."
