Sound Thinking is a virtual chord and scale encyclopedia—a free, online chord finder and scale wizard at Theoretically Correct. Use it to explore chords, scales, and arpeggios for any stringed instrument in any tuning. Sound Thinking simplifies difficult concepts by making music theory easy to visualize and understand.
There are a number of ways to launch Sound Thinking. When launched directly it opens with its default settings displaying:
When you launch Sound Thinking to a "scene" it shows a predefined setup, for instance, a specific instrument, with a specific chord, scale and root. You can save any setup to a scene.
Scenes can be simple or relatively complex. A simple scene usually contains a single instrument displaying a chord map or scale map.
The links on this page launch Sound Thinking and open it to a predefined scene. (Presently there are you may see instrument windows with scroll bars showing; if so just resize the window to make them disappear. This will be fixed soon.)
Here's a simple guitar chord scene: Guitar chords in standard tuning (EADGBE). When the scene opens it shows a guitar in standard tuning displaying an E chord map. You can easy select a different root, chord type, or scale. In other words, a scene is just a starting point.
Here's a simple scene for viewing scales on mandolin; it initially shows an A major scale displayed horizontally: Scales on Mandolin. By picking a different root you can view a scale map for any other major scale. Or you can select other scales from the scale tab.
A complex scene usually includes multiple instrument windows. Each window contains one instrument, and each instrument possesses a number of properties:
The scene also holds the window size and positioning information.
A "comparison" scene usually presents two or three instruments situated side by side. The purpose may be to contrast the differences or similarities between tunings. It may be to show chords and scales side by side, or to illustrate the effect of a capo or partial capo.
It can easily take a few minutes to manually construct a comparison scene. Fortunately the links on this page save you effort trouble. Of course Sound Thinking provides menus for selecting an instrument and the instrument's tuning, and the chord or scale you want to view, and the steps required are relatively simple, but it's just simpler to use a predefined scene.
Once in Sound Thinking you can alter any existing scene, you can clear all existing instruments and create a scene from scratch ... and you can "save" the resulting scene. Just click the "URL button" and Sound Thinking puts a URL on the clipboard. You can paste the URL into an email, paste it into a browser's address field (and bookmark it for future reference) or place the URL in an online article, just like the links on this page. Saving a scene is particularly handy if you've created a complex "comparison" scene to which you'd like to return.

A single click may reveal or clarify music information or relationships that you
may be new to you.
Guitar: A major chord (no capo) • A major chord (capo 2) • G major chord (no capo) (Note names)
There is an extensive article on partial capo here at TheoreticallyCorrect.com
Partial 330033 — Requires a capo like the Spider or Third Hand capo
These scales have the same fingering, and the same notes. The difference is the root, formula and perspective. In other words, they are modes of each other.
Same notes, different tonal center and thus different formulas
