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: β€’ Minor 7 (1, b3, 4, 5, b7) β€’ Minor 6 (1, b3, 4, 5, 6) β€’ Minor 7b5 (1, b3, 4, b5, b7) β€’ Major b6 (1, 2, 3, 5, b6) β€’ Major b2 (1, b2, 3, 5, 6) β€’ Whole-Tone (1, 3, #4, #5, b7) Smart Chord Filtering Choose from 14 chord filters to match the sound you want: Major, Minor, Dominant β€” 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 β€” 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 β€” based on harmonic fit, not guesswork. Across all keys and chords, that’s 7,896 ways to explore expressive sounds. Stay in the Flow β€’ Save your favorite combinations for fast recall β€’ History tracking keeps your recent choices just a tap away β€’ Built-in suggestions point you to the most musical options Who It’s For β€’ Musicians breaking out of tired scale shapes β€’ Improvisers searching for expressive new ideas β€’ Composers seeking color and clarity β€’ Teachers looking to simplify complex harmony β€’ Students learning how theory works in real music Explore. Visualize. Improvise. Pentatonics isn’t just a scale reference. It’s a launchpad for creative growth. Built for modern iOS with a clean, fast interface powered by SwiftUI, it’s designed to keep you thinking less about theory β€” and more about sound. Take five β€” and play like never before!

About

Scale Syllabus

Read full description

Scale Syllabus puts the 253 scales of Complete Scale Syllabus by Gianluca Barbaro in your pocket, and lets you see, hear and transpose every one of them. The scales are not a stored list. The app rebuilds them with the algorithm the book itself was made with: every seventh chord, every combination of available tensions, folded together by rotation. That is why the numbering matches the printed page exactly β€” scale 145 here is scale 145 in the book. WHAT YOU CAN DO β€’ See any scale in standard notation, on a piano keyboard, or on a guitar or bass fretboard β€’ Transpose to any of the twelve keys, with each note spelled the way a musician would write it β€’ Start from any degree: pick a mode and the scale is shown from that note, in the key you chose β€’ Hear a scale or any of its chords, ascending or arpeggiated, with the notes lighting up as they sound β€’ See the triads and four-note chords every degree carries, inversions included, and view any of them the same three ways β€’ Read the fretboard as a whole map, or touch a fret for the run one hand can play from there β€’ Ask for a chord and the neck answers with shapes a hand can really hold β€” tap again for the next one β€’ Walk through the sixteen ways a four-note chord can be laid out inside two octaves of keyboard β€’ Choose your instrument once, and clef, written octave and transposition follow β€’ Find a scale from the notes themselves: play a phrase into the microphone, or type the note names, and the app lists the scales that contain them and says what chord they make β€’ Follow the relationships: which scales contain this one, which ones it contains, and which are a note away β€’ Print a scale as a sheet of engraved music, export it as PDF, or share it β€’ Read six short chapters of music theory, with figures the app draws itself β€’ Mark favourites and keep your own written notes on any scale A guided tour goes through all of it the first time you open the app, and it can be replayed whenever you like. The app speaks English, French, Spanish, German, Italian, Japanese and Chinese, and you can look for a scale in your own language. The names of the scales themselves stay as the book prints them. WHAT MAKES IT ACCURATE The book's own derivation quietly loses four chord types, and with them five scales. This app generates them too β€” appended at the end, so that not a single number from the printed book moves. Note spelling follows musical function rather than whatever is cheapest to compute: a minor seventh chord is written C Eb G Bb, never C D# G A#. FREE AND COMPLETE Three scales are always open: major, harmonic minor and melodic minor β€” and with the major come all its modes, natural minor included. You can open two more of your choice, and the ones you open stay yours. A single purchase opens all 258 scales and unlocks printing, PDF export and sharing β€” no subscription, no account. Nothing you write leaves your device. The app has no accounts, no advertising and no tracking of any kind, and what you play into the microphone is analysed as it arrives and never recorded, stored or sent anywhere. Reports of wrong or missing scale names are welcome: me@barbaro.it

Verdict

The call

The clearest difference is price: Scale Syllabus at Free against Pentatonics's $0.99. Scale Syllabus also leads on device support (4 vs 2) and iOS requirement (15.0 vs 17.6). Pentatonics's advantage is in-app purchases (none vs 1) and chart position (#179 vs unranked). On ads there is nothing between them.
