Harmonie tonale vs FretCipher

You play a progression, it sounds right, and you could not say why. Harmonie answers that question, helps you write what comes next, then drills you until the answer comes on its own. Enter a progression and the app shows what each chord does, its degree, its function, and the cadence that closes the phrase. WHY, NOT JUST WHAT Most chord apps name things. This one explains them. Why a borrowed iv darkens the arrival on I. Why a tritone substitution keeps its pull. Why V going to vi leaves the phrase open. The leading tone is named, and so is what it pulls towards. WRITE Under your progression, the app suggests the chords that can follow, from the most expected to the most colourful: authentic cadence, interrupted cadence, secondary dominant. One tap adds it. Loop the progression at the tempo you choose, and save it for later. SEVENTHS, TENSIONS AND MODES Switch the palette to seventh chords, with their formula in degrees, written the classical way (Cmaj7) or the jazz way (CΔ, D-7). On every chord, the app tells you which mode it is played in at that point, which 9ths, 11ths and 13ths sound, and which ones to handle with care. Beyond major and minor, twenty modal keys, from Dorian to Phrygian dominant, each with its characteristic note. PRACTICE Short sets that never repeat. Name a degree, name a cadence, find the key, figure an inversion, count the accidentals in a key signature, name a mode, spot the tension that clashes, pick the next chord. Three levels, and every answer is marked and explained. TRY SOMETHING ELSE On any chord, the app offers what harmony allows in its place: tritone substitution, secondary dominant, ii-V, borrowed minor subdominant, Neapolitan sixth, interrupted cadence. One tap and you hear the difference. SEE AND HEAR A keyboard and a guitar fretboard where the notes of the chord light up. Real staff notation, or guitar tab with several positions per chord. The circle of fifths, with its neighbours and its relative. Transposition, to compare two keys by ear. WRITTEN IN ENGLISH, NOT TRANSLATED The English here was written by hand, in the terms English-speaking theory actually uses. I-vi-ii-V is a rhythm changes turnaround, not a French anatole. V to I in root position is a perfect authentic cadence. V to vi is interrupted, and deceptive is given alongside it, because the two traditions disagree and you may have learned either one. Note names are a separate setting, independent of the language. On first launch, tell the app what you play and it sets itself up. NOTHING ASKED OF YOU No account, no ads, no tracking.
