JPS is a dictionary of jazz vocabulary — short, pattern-tagged phrase examples drawn from how Wes Montgomery, Grant Green, Charlie Parker, and Joe Pass actually play over the changes you're working on. Browse Artist Packs, Tune Packs, and Progression Packs — pick the patterns you want, practice them, sound like the records.
You've practiced for years. You know your scales, your arpeggios, your ii–V–Is. But when you call a tune, your solos still sound like patterns — not like the records that made you fall in love with this music.
The path most teachers prescribe — transcribe Wes solos, organize them, build practice plans for every tune — works. It also takes ten thousand hours and a master's degree in music librarianship.
Most players never get there. Not because they're lazy. Because the overhead is insane.
Hundreds of short phrase examples — the common vocabulary and recurring patterns your heroes use across their solos. Each phrase is transcribed by ear from the original recordings, then re-recorded by working jazz musicians for clean, isolated reference audio. We don't stream the masters. Every clip is ours. Real language, ethically clean.
Real phrases organized and accessible by artist, chord type, key, progression, Essential Jazz Pattern, and more. Browse curated Artist Packs, Tune Packs, and Progression Packs — or filter directly to find your next favorite phrase to play in under 10 seconds.
Every phrase is tagged with Chase's nine Essential Jazz Patterns — the recurring "words" that build every solo. Pick the tune you're studying, get the phrases your heroes played there, practice at the tempos you can play right now.
Pick a tune. Filter by chord context, key, or hero. Find your next favorite phrase to play. Practice it at slower tempos before pushing to performance speed. Tag what you've learned. Move on.
When you open a phrase in Practice Mode, the flashcard plays the audio before revealing the notation. You hear how it’s supposed to sound, then mimic it — like a child hears “hola” before they ever read “hola.” The notation stays one click away as a reference; the audio is the lesson. (Browse and Library views show notation by default — Practice Mode is where the flashcard flow happens.)
Each phrase is recorded at three tempos — 80, 100, and 120 BPM — so you can build up to performance speed gradually. Loop a phrase to internalize it. Toggle the metronome click to lock in time. Use the count-in so you start clean. Reveal the notation only if your ears get stuck.
Rate each phrase as you go — Missed, Almost, Got it. JPS schedules the next review at the moment you’re about to forget. Three “Got it”s in a row and the phrase graduates to Mastered. Slip up later and it drops back into rotation. The spaced-repetition algorithm at the heart of this is the same one Anki and Duolingo use — battle-tested in language education for decades.
The flashcard methodology behind Anki, Duolingo, and university language programs — applied to jazz vocabulary for the first time.
JPS is where you find and learn the phrases. To turn them into solos, you need grammar (the Essential Jazz Patterns), reps (live coaching), and a community keeping you accountable.
Chase's Guitar Academy is the membership where the Jazz Phrase System lives — full curriculum for tunes, weekly live classes, and a global community of jazz guitarists.
“It's like a Rosetta Stone for unlocking the language of jazz. I learned more in the first four weeks than four decades of playing.”Matt Drummond · CGA member, 1.5 years
“The software actually picked phrases I wanted to learn and use in a solo — at my level, motivating, and ones I could use in songs I'm working on. I get prompted by an audio recording and not the music/tab. It helps with my ear training and connects the sounds to my fingers.”
“I had a lot of fun playing around with this over the weekend. Each phrase is short enough that I can pick up a few in a practice session, and the spaced review is a great addition. The Founder's price is fair for a year's access as you build out the library — I'll probably be signing up.”
“So far I am super impressed! I really like the way you organized the database. This will be a major vocabulary booster. Look forward to working with this system.”
“I was playing through a bebop head and noticed some notes I was playing were part of one of the phrases in my practice pack. Immediately there was context around what I was playing, instead of just being a memorized line.”
“I LOVE it! Easy to use, great written transcriptions & clean audio. This is worth good money.”
“Really liking it so far. An hour and some change just melted away.”
“Going to pay for JPS right now. Great work. Congrats.”
“Amazing tool… this really helped me internalize the language.”
“Just what I had been looking for. It is really helping with my development in ear training.”

Chase Maddox is a jazz guitarist, educator, and former Calculus teacher who runs Chase's Guitar Academy. He built JPS to bridge the gap his students kept hitting: they knew the tunes and the improv concepts, but the actual jazz language the masters played stayed locked behind years of solo transcribing.
JPS turns that into a ten-second answer — pick a tune, see the phrases your heroes played over those changes, get back to your guitar.
