Get instant 4-voice harmonization with voice leading on one single click - loading a single-voiced audio file - and create natural sounding background choirs and brass arrangements!

vielklang allows you to completely focus on the musical issues rather than technical or theoretical ones, since vielklang is not just a harmonizer; it 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 voice pitches automatically selected to sound most natural (voice leading).

You never have to bother about things like root note, scale, tuning frequency, harmony progression, voice leading etc., although you can, if you want to.

With vielklang, you can thus easily generate and prototype natural sounding background vocals and brass sections, modify melodies and single-voiced loops in terms of pitch and scale, and experiment with different harmonizations or chords triggered by different MIDI-inputs. It allows you to generate four voices, edit their harmonies and single pitches, and convert the audio to MIDI.
