See how chord progressions work, explore their function on an interactive tonal map, reharmonize them, and practice the results with accompaniment.
Mapping Tonal Harmony Pro combines functional harmonic analysis, chord-scales, Roman numerals, arrows and brackets, tonal maps, reharmonization tools, backing tracks, and all-key practice in one environment.
Mapping Tonal Harmony Pro does more than display chord symbols and play accompaniment. It organizes harmony by function, shows how chords relate inside a key, analyzes progressions, connects chords to chord-scales, and keeps the map synchronized with the music you are studying.
Move from understanding the progression to hearing and practicing the musical result without leaving the same environment.
Instead of treating every chord as an isolated symbol, the map organizes tonal harmony around function. Tonic, subdominant, dominant, secondary dominants, substitutions, and related harmonic regions become part of one navigable structure.
Change key and the harmonic relationships remain visible. The map gives students, improvisers, arrangers, and composers a way to understand why a chord works—not just what chord comes next.
Follow the written chords while Mapping reveals the functional and scalar information underneath them.
Keep the practical progression visible while studying its deeper structure.
See each chord in relation to the active key and tonal center.
Visualize dominant motion, ii–V relationships, and connected harmonic paths.
Pair chords with scale choices directly in the analysis.
Follow changes of tonal center as the progression moves through different keys.
Hear the music while the score, analysis, and map stay connected.
Use the same harmonic system as a practice environment. Hear progressions with accompaniment, move ideas through all 12 keys, and connect chord-scale choices to the functions you see on the map.
The Reharmonizer lets you experiment with alternate chord choices while the score and map remain part of the same harmonic environment.
Work with secondary dominants, diminished harmony, tritone substitutions, modal interchange, dominant variations, extended dominants, melodic-line clichés, bass-line clichés, and other reharmonization strategies.
Expand the core Mapping environment when you want more focused improvisation, voicing, and repertoire study.
Focus on important notes through a progression and practice connecting harmonic targets deliberately.
Explore triads and quartal structures over chords to expand voicing and improvisational color.
Study a large repertoire library with Mapping’s harmonic analysis and practice tools.
Explore reharmonized versions of standards and compare alternate harmonic possibilities in context.
Start with the core ideas, then explore analysis, practice, and reharmonization.

A conventional backing-track app can play a chord progression. Mapping also analyzes the progression, places the chords inside a functional tonal system, shows Roman numerals and chord-scales, and connects the analysis to the map while you study or practice.
Yes. Mapping Tonal Harmony Pro includes harmonic analysis tools that display chord symbols, Roman numerals, chord-scales, arrows, brackets, and changes of tonal center while keeping the analysis connected to playback and the map.
The tonal map is a visual organization of harmony by function. It shows relationships among tonic, subdominant, dominant, secondary dominants, substitutions, and related harmonic regions so that the logic of a progression is easier to see.
Yes. The app includes accompaniment and 12-key practice tools designed to turn the harmonic concepts you are studying into playable exercises.
Specialized add-ons include Target Notes, Upper Structures, Jazz Standards, and Jazz Standards Reharmonized. They extend the core Mapping environment with additional practice, voicing, and repertoire material.
The iOS and macOS apps provide the interactive analysis, playback, backing tracks, and practice environment. The PDF is a portable version of the tonal maps that works on PDF-capable devices but does not include sound.
No. They are currently separate App Store purchases.
No. The map can be used as a visual introduction to functional harmony, while more experienced musicians can use the deeper analysis, chord-scale, reharmonization, and practice tools.
Analyze the progression, explore it on the map, hear the alternatives, and turn the same harmonic ideas into practice.
