Are you interested in tonal harmony? Do you want to test your melody with harmony? MelodyHarmonizer is built for musicians, composers, and improvisers looking for new harmonic ideas. With MelodyHarmonizer, you can generate a wide variety of unique harmonizations for any melodic line you provide. Whether your input melody is tonal, chromatic, free-tonal, or even twelve-tone (dodecaphonic), the app explores what kinds of harmonic progressions can be applied to it. A Tool for Harmonic Exploration: MelodyHarmonizer is intentionally not based on standard probabilities. This means it does not necessarily produce a fully polished or the most commonly heard harmonization. Instead of forced, conventional coherence, it opens up unexpected harmonic paths and challenges your musical routine. Key Features: • Control the strength of suggested modulations. • Exclude unwanted chords from the harmonization rules. • Adjust the playback tempo of the harmonized melody. • Fine-tune relative note durations without affecting the underlying harmony. Discover tonal harmony in new contexts and expand your musical creativity with MelodyHarmonizer!
