Harmonize your melody with one single click - loading a single-voiced audio file - and create natural-sounding background choirs and brass arrangements!


It's all about Music
vielklang "thinks musically" and prepares the ground. vielklang by zplane is packed with musical intelligence and music theory: it automatically detects the best fitting harmonies for each individual input melody, and automatically synthesizes up to four voices with the voices not merely running in parallel but with their voicings automatically selected to sound most natural (voice leading). vielklang gives you a natural-sounding result immediately and allows you to concentrate on tweaking the results rather than edit them from scratch as with traditional harmonizers.
