Raga Yaman (Kalyani)
Yaman is a seven-note Hindustani raga, a melodic framework, with a raised fourth; Kalyani shares its scale but uses different phrasing and ornaments. Traditionally associated with evening, Yaman can sound serene or devotional; hear its character through Ni Re Ga, starting below Sa, the home note.
What is a raga? A plain-language guide for listeners
A raga is a melodic framework in Indian classical music for creating pieces and inventing melody during performance. Listen for four things: which notes appear, how the melody moves, where the musician lingers, and which short phrases return.
Thaat and melakarta explained
A thaat in Hindustani music and a melakarta in Carnatic music are seven-note parent scales used to organise ragas, the melodic frameworks musicians perform. Hindustani music uses 10 practical categories, while Carnatic music uses 72 allowed scale combinations; these help identify note relationships, not a raga’s phrases or character.
Raga vs scale: what Western musicians get wrong
A raga adds rules for movement, emphasis, identifying phrases and ornamentation to a scale or mode, a scale with a home note. Producers lose its identity when they treat it as a note list, ignore its tuning and phrasing, or let changing chords reshape the melody’s meaning.
Questions people ask
Is the online mastering tool free?
Yes. Mastering a track is free, with no subscription and no hidden fees. An account keeps your masters in your dashboard.
What loudness does the tool target?
Loudness is measured in LUFS and you set the target. Around minus 14 LUFS suits streaming platforms; the tool also controls true peaks so the master does not clip after encoding.
Which file formats can I upload?
WAV, MP3, FLAC and AIFF. Upload the final mix with a few decibels of headroom rather than a limited or already mastered file.
