What this site is for
Chord Warrior maps how scales connect and nothing else: which family a mode belongs to, which modes sit one altered degree apart, and where each family’s mirror image lands. It draws no instrument, plays no sound and gives no scale a page of its own, which is exactly why it needs the rest of the network.
Once a scale has a place on the map, the questions that follow belong elsewhere — how it lies under the hand, what it sounds like and why, how a style puts it to work. Every site below answers one of those.
Where a scale goes next
String WarriorOnce you know which voice steps where between two chords, the hub is where to find both chords under your fingers, on whichever of twenty-odd instruments is in your hands.
Theory WarriorThis site measures how far each voice travels from one chord to the next. That site explains why the shortest way usually sounds smoothest: the tendency tones, the bass and the parallels to avoid.
Keys WarriorThis site counts voice leading in pitch classes, with no register. That site plays a progression voice-led on the keyboard, each chord voiced near the last, so the counts become hands.
Ukulele WarriorFour strings hold four voices, and a common tone between two chords is often a string that keeps its fret; that site draws every chord shape on the ukulele.
Bass WarriorThe calculator pairs every voice but treats none as the bass. That site is the instrument that chooses the bottom note, with every chord and line charted on its fretboard.
Mandolin WarriorThree-note chords on a neck tuned in fifths often keep two fingers and step the third; that site draws every chord voicing the mandolin family plays.
Guitar WarriorMost players meet voice leading as one finger sliding a fret between two guitar chords. That site teaches every chord shape on every guitar in the family.
Banjo WarriorAn open-tuned banjo leaves some voices ringing on open strings while others fret a step away; that site covers the tunings and the chord shapes that follow from them.
Fiddle WarriorA fiddle plays two voices at once in double stops, so a common tone is a finger that stays put; that site is the violin family's fingerboard.
Ear WarriorThis site counts the semitones each voice travels. That one trains the ear to hear a single one of those steps — the interval between two notes, heard and named with the page blank.
Bluegrass WarriorA bluegrass band splits a chord among its seats, and each player takes a voice to the next chord. That site is the band itself: the seats, the jam and the repertoire.
Music Warrior NetworkThe map of every sister site, for the reader who came to measure two chords and now wants the site that owns the instrument or the style they are played in.
Nashville WarriorA Nashville chart writes a song's chords as numbers up the major scale in any key. That site owns that chart; this one measures how the voices get from one number to the next.
Mariachi WarriorA mariachi son gives its harmony to a whole section of players, each holding a voice of the chord; that site reads those forms section by section, for the ensemble.
Jazz WarriorJazz players guide a tune's thirds and sevenths from chord to chord a semitone at a time. That site starts from a named standard and shows what players do with it on the bandstand.
Country WarriorA country record gives each chair its part in the harmony behind the singer. That site maps those parts; this one measures how each voice of a chord reaches the next.
Tres WarriorA Cuban montuno cycles its figure over a few chords, the same tones held from one to the next; that site is the tres and the patterns it plays over the harmony.
Sitar WarriorHindustani music grows from a drone and a melody rather than from chords in sequence, which is where this calculator has nothing to say; that site is the sitar and its ragas.
Oud WarriorMaqam music builds its melody from cells with intervals no twelve-note chord holds, which is where these counts stop; that site is the oud and the maqamat it plays.
Cuatro WarriorThe Puerto Rican and Venezuelan cuatros strum full chords in a handful of keys; that site is both instruments, their tunings and the strokes that carry the harmony.
Charango WarriorAndean songs often turn between a minor chord and its relative major, two triads that share two of their three tones; that site is the charango that plays them.
Cavaquinho WarriorChoro threads chromatic passing chords between its main ones, each a semitone step away in one voice; that site is the cavaquinho at the heart of choro and samba.
Gear WarriorA voice-leading answer is the same on any neck, but the strings it is played on are not: that site solves gauges and tension for a whole set and says which company made them.
Blues WarriorThis site measures two chords at a time. That site plays a twelve-bar form, bar by bar, and marks each note against the chord under it as a chord tone, a colour or a rub.
Flamenco WarriorFlamenco's cadence steps its chords down a semitone at a time in the top voice. That site says which palos use it and where on the twelve-count cycle each one's accents fall.
Progression WarriorThis site measures how the voices travel between two chords. That site reads a whole chord line in its key and names what each chord does there.
Pedal Steel WarriorThis site counts the semitone steps between two chords. A pedal steel makes those steps with its feet and knees, and that site shows which pedal or lever raises or lowers which string.
Scales WarriorThis site measures the distance between two chords; that site measures the distance between two scales, and lists every mode one altered degree from another.
Music Warrior AIThis site measures two chords against each other. That site is for asking about one from inside an AI assistant: its notes in any key and the chord page for the instrument you name, cited as the source.
How the network divides the work
Almost every site in the network publishes scales of its own; none of them maps how the scales relate. That split is deliberate: the instrument sites draw them, the theory site gives each one a page, the style sites play them, and this site shows where each one sits among the rest.
Sisters still being built are not in the list yet. Each joins the day it opens, on the same terms as the rest — one subject, one home, and a straight sentence here about why you would leave for it.
