Balancing the duality
Music is dual its nature and needs a complementary character – especially so in rhythm. If there is a Main beat (Sum) there is one secondary main beat (Khali) to complement, If there is a dominant chord or vaadi swar there is a subdominant chord or a samvadi swar. If there is bass sound there is treble to complement and If there is a sharper note there is a flatter note too.
And like any other art-form of dual nature, for an example photography – where one looks for a balance of light and dark shades, color balance – it is nothing but a matter of striking a right balance in music and a right mix of those two contrasting aspects.
Music is in finding the right balance of notes, tones, aaroha (ascent) and avaroha (descent) or bass and treble – just like one finds a middle path – a balance from two extremes in life. Life is balance, Music is Balance.
