What this site is for
Ear Warrior drills recognition and nothing else. An interval, a chord quality, a progression: you hear it, you name it, and the site tells you whether you were right. That is the whole subject, and it is why no address on this site carries a note. A minor third sounds like a minor third wherever it starts, so a page per starting pitch would be twelve copies of one page — and twelve copies of one page is the shape this network refuses to publish.
The price of that is real. This site can confirm that what you just heard was a minor sixth; it has nowhere to put your hand afterwards. Every site below has somewhere, and between them they cover every instrument the network teaches.
Who to ask once you have the name
String WarriorOnce you have named the chord, the place to see it laid out on whichever of twenty-odd instruments happens to be in the room.
Theory WarriorThe nearest relative this site has: the same intervals and the same keys, arrived at by reading and reasoning rather than by listening.
Keys WarriorTwelve pitches per octave, fixed by whoever tuned the thing before you arrived, is the assumption every drill here rests on. That site is the deep home of the instruments that made it normal, sorted by how many notes each can sound at the same time.
Ukulele WarriorFour strings with one tuned above its neighbours, which reorders the notes of a chord in a way your ear picks up long before you can explain it.
Bass WarriorThe line you were following underneath a progression here, turned into something you can play rather than something you can only identify.
Mandolin WarriorWhen a tune you can already hum has to become a physical thing, on an instrument tuned so that one grip covers all twelve keys.
Guitar WarriorThe shapes behind most of the chords in these drills, and the retunings that quietly change what a familiar sound is actually made of.
Banjo WarriorFive strings and a picking hand, where the repeating patterns your ear keeps hearing under a bluegrass chord are taught as technique.
Fiddle WarriorThe instrument with nothing marking the pitches, where this site’s subject stops being an exercise and becomes the only way to play in tune at all.
Bluegrass WarriorOne genre’s worth of context for what you keep hearing: which chords a circle actually calls, in which keys, and in what order.
Music Warrior NetworkDrills here train the ear and nothing else; that site is the map of where to take what the ear has learned — one card per sister, the instrument or subject each owns, and which to open first.
Nashville WarriorHearing a change as the four rather than as F is the skill every drill here builds. That site is where the same relative thinking gets written down and read at speed, which is what makes it portable to all twelve keys.
Mariachi WarriorA whole group sounding the same chord at the same instant, with the low end doubled an octave below: a dense, deliberately blended sound that is unusually hard to pull apart. Good practice for hearing inside a block rather than naming it.
Jazz WarriorEvery drill here asks you to name what you heard. That site is where naming it is not enough — one chord can be swapped for another that does the same job and sounds almost the same, and catching which one went past is the whole skill.
Country WarriorMost of what you hear in this music is not the melody. It is a handful of parts holding different beats at once, and that site names each one and says what it plays while the others are busy — good practice for pulling a single line out of a full recording.
Tres WarriorA figure that repeats until you stop noticing it is the hardest thing to hear accurately, and Cuban son is built almost entirely from those — worth the trip once twelve possible answers have stopped surprising you.
Sitar WarriorThe drills here stop at twelve equal steps because that is what an exercise can grade; a raga's ornaments move through pitches no interval quiz can name, and that is the site for hearing what your ear has not yet been asked to hear.
Oud WarriorInterval quizzes here have twelve possible answers. Maqam practice names and teaches pitches that are not among them — a whole trained vocabulary for distinctions this site’s exercises cannot yet test you on.
Cuatro WarriorOne of its two instruments folds a course down inside its own range, so the highest-sounding note is not the one the tuning would lead you to predict. That is a genuinely hard listening problem, and a good test of whether your ear tracks pitch or position.
Charango WarriorA five-course tuning that does not climb in pitch order, so a familiar chord arrives with its notes stacked in an order you would not predict. Good practice for hearing what is actually on top rather than naming the chord and moving on.
Cavaquinho WarriorSamba is easy to recognise and hard to reproduce, and the reason is rhythmic rather than harmonic. That site takes the pattern apart beat by beat, which is the missing half of hearing a groove and being able to say what it was.
Gear WarriorEar training needs no equipment at all, which is exactly why the gear questions that arrive here have nowhere to land — they land there.
Blues WarriorThis site trains you to hear the four chord arrive. That site writes down what is sounding against it in a blues: which blues-scale notes are chord tones, colour or a rub in each bar of four forms.
Flamenco WarriorThis site trains the ear on pitch. That site writes down the other half of hearing a palo: where its accents fall on a twelve-count cycle, and whether they line up with a count in twos or in threes.
Progression WarriorThis site trains you to hear a progression with nothing written down. That site starts from the chord symbols instead: type a line and it reads the key, the numerals and the moves off the page.
Pedal Steel WarriorThis site trains the ear to hear a chord change. That site shows how a pedal steel makes one without moving the bar: which pedal or knee lever retunes which string, drawn change by change on the E9 and C6 necks.
Scales WarriorThis site trains you to recognise a mode by ear. That site shows what sits next to the one you just named: the modes one altered degree away, and the family each belongs to.
Music Warrior AIThis site trains you to hear a chord. That site is for the moment you want its spelling handed to you inside an AI assistant: the notes and degrees a voicing sounds on your instrument, read from this network's data and cited to the page that owns it.
Chord WarriorOnce you can hear one interval, the next question is how a whole chord reaches the next. That site counts it: each voice's step in semitones between two chords, the cheapest pairing first.
How the network divides the work
Every other site in the network is organised around an instrument and a note: this thing, in this key, in this place. This one is organised around neither, on purpose. A tritone keeps its identity wherever you move it, so there is no note anywhere in the addresses here and no instrument to hang one on. That is what makes the doors above load-bearing rather than decorative: the answer to “where do I put this?” genuinely is somewhere else, every time.
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.
