About
Hookpad by Hooktheory is a smart songwriting software that merges music theory with AI-driven assistance to help any level of musician create compelling chord progressions and melodies. Whether you're a singer-songwriter, beatmaker, producer, or music educator, Hookpad removes the guesswork from composition by surfacing only the chords that work in your chosen key—no wrong notes, ever. At its core, Hookpad features a color-coded visual system that highlights both chords and melody notes by their harmonic function, making it easy to understand why certain combinations sound great together. You can connect a MIDI keyboard to play ideas in directly, or upload your own audio track and build chord structures around it. Hookpad is powered by TheoryTab, the internet's largest database of songs broken down by music theory—over 70,000 songs serve as inspiration and reference. The platform also includes Aria, an AI composition assistant, and integrates with the Hooktheory ecosystem including interactive music theory books and gamified ear-training with ChordCrush. Hookpad is ideal for songwriters looking to write smarter, music students wanting to apply theory in practice, composers sketching ideas quickly, and educators teaching harmony in an engaging way. The tool runs entirely in the browser (Chrome, Firefox, Safari, Edge, or Opera) and offers a free tier alongside premium pricing plans.
