Pentatonics vs Thelonious

Pentatonics - Take Five Less notes. More music. Visualized. Step back. Level up. Unlock a new world of musical expression with Pentatonics, the visually driven music theory tool that transforms five-note scales into endless creative possibilities. Whether you’re improvising, composing, or exploring harmony, Pentatonics shows you how to say more with less. What Makes It Different Visualize the Scale-Chord Connection A one-of-a-kind pentagon visualizer shows exactly how a scale maps onto a chord, highlighting chord tones, extensions, tensions, and color with instant clarity. Six Curated Pentatonics These aren’t basic box patterns. Each scale is chosen for its harmonic purpose: • Minor 7 (1, b3, 4, 5, b7) • Minor 6 (1, b3, 4, 5, 6) • Minor 7b5 (1, b3, 4, b5, b7) • Major b6 (1, 2, 3, 5, b6) • Major b2 (1, b2, 3, 5, 6) • Whole-Tone (1, 3, #4, #5, b7) Smart Chord Filtering Choose from 14 chord filters to match the sound you want: Major, Minor, Dominant — plus altered, sus, and extended voicings like #11, b9, b13, and more. Two-Way Transposition Transpose chord and scale roots independently. Practice in any key. Compose in any context. Teach with full flexibility. Layered Interval Insight Switch between note names and scale degrees to understand how each note functions inside the harmony. Highlight Chord Tones Color-coded overlays show you roots, thirds, sevenths, and more — helping you target the strongest notes in your lines. Smart Starting Points Pentatonics finds 47 unique entry points where each scale fits the chord best — based on harmonic fit, not guesswork. Across all keys and chords, that’s 7,896 ways to explore expressive sounds.
