Made with Sur
Derived from the sacred languages of Sanskrit and Hindi, Sur (सुर) embodies the concept of expression within each musical note or tone, serving as the foundational element of the composition and performance of Indian classical music. It represents the intrinsic connection between the artist and the divine, where each note becomes a vessel for spiritual expression and aesthetic beauty.
At its core, Sur aims to offer a definitive Drone or 'Shruti' experience. Whether you seek to create a harmonious bed for ambient compositions, engage in raga and modal improvisation over an inspiring and evolving background, accompany Dhrupad singing in Nada Yoga, or enhance your meditation practice, Sur provides the foundational instrumentation necessary for musical exploration and spiritual elevation through the drone.
Central to Sur are two essential instruments: the male and female Tanpuras, and the Shruti Box. The Tanpura, with its resonant strings and gourd body, serves as the grounding force in Indian classical music, enveloping listeners in a meditative aura while defining the tonal centre of a composition or improvisation, both tanpuras were custom-made for us by the renowned tanpura-luthier Naeem Sitarmaker hailing from the legendary instrument making capital of India Miraj. Additionally, the Shruti Box, an adaptation of the Harmonium, offers players the perfect tool for self-accompaniment through its relatively passive playing style and endless tones. Sur goes beyond tradition, offering a selection of creatively processed samples that transport the idea of the drone into a new dimension ( fully explored in our Portal's series instrument – Naada). We firmly believe that traditional musical cultures should not be viewed as history but as living and evolving practices, embracing the present moment while firmly rooted in thousands of years of development.
Powered by our advanced MNDALA 2 engine, Sur features a deep micro-tuning system, allowing users to finely tune each note. Including preset tunings informed by the teachings of Dr. Vidyadhar Oke, Sur invites musicians to explore the intricate nuances of popular Ragas with precision and authenticity. We created Sur as a testament to the drone's sacred beauty and boundless potential within Indian classical music and beyond, inviting musicians on a journey of sonic discovery and spiritual resonance, regardless of genre.
Tanpura (Combined, Female, Male)
Integral to Indian classical music, is a plucked string instrument notable for its role in providing a continuous drone that enriches the music’s melodic and rhythmic flow. This instrument, with its meditative and harmonious sound, features a hollow body traditionally made from a gourd and a long neck, with four strings tuned to the raga being performed. The Tanpura samples in this instrument map were crafted by the renowned Naeem Sitarmaker from Miraj, and performed for optimal sound quality and resonance that faithfully represents this classic instrument’s essence.

Shruti Box Long
The Shruti Box, an essential accompaniment in Indian classical music and sound meditative practices, is a hand-operated reed instrument used to provide a drone in a fixed pitch or pitches. Known for its rich, harmonious sound, the Shruti Box supports vocalists and instrumentalists by offering a stable tonal foundation that enhances the overall musical performance. Its simple design allows for continuous airflow through reeds, producing a sustained sound that can be adjusted to match the specific pitch requirements of any performance.
