Chordify vs HarmonyBuilder

Chordify turns music from YouTube, SoundCloud, or a private collection into chords aligned with an interactive player. Its catalog search covers YouTube, SoundCloud, and 36 million songs already chordified. Chordify uses deep neural networks to recognize chords and track beats, letting players work with guitar, ukulele, piano, or mandolin; mandolin is available only on the website and Android app. Web and mobile versions share chordified or favorited songs. The Toolkit includes a chromatic tuner, metronome, chord practice, and live chord detection, with all Toolkit features unlocked in Premium Plus. Chords can be exported as PDF or MIDI, and songs can be embedded on websites or blogs, although edits are not supported in embeds. A free plan is available. Basic costs $24 a year, Premium costs $42 a year, and Premium Plus costs $54 a year, each billed yearly. Deezer songs are unavailable, and Deezer links work only on the website.

HarmonyBuilder is music notation and composition software for writing and hearing four-part harmony. Its editions range from score creation and MIDI export to harmony instruction, composition tools, and teacher-student collaboration. Basic supports moving notes and experimenting with harmony and rhythm. Educational checks voice-leading errors, color-codes chord notes, and identifies and names chords. Professional adds a Chord Selector wheel, a Voicing Generator, and tools for harmonizing melodies or bass lines. Institutional provides a dedicated database for sharing assignments, homework, and compositions; its score accounts are password-protected. Compositions can be saved to a computer or public web archive, or in MIDI format, and a private link can open a score in a browser. HarmonyBuilder runs on Windows, Mac, and Linux, and requires Java 6 or higher. The trial lasts up to 28 days and includes Basic, Educational, and Professional functionality. Basic costs $14 a month; Educational costs $49 a month.
