Cosmo Welfare


Cosmo Welfare is musician, frequency researcher and discoverer
of the universal tuning system, called
Natural Tuning.
Natural Tuning consists of the pitch reference frequency and of pure intervals, whose frequency ratios are the quotients of natural numbers.
All is based on the natural overtone series.

Natural Tuning begins with 1 Hz and includes 432 Hz as well as 256 and 440 Hz.

Just (pure) intonation is the only natural interval design and is the heart of
Natural Tuning.
