About

Jazz Catalog

Features
Read full description

The jazz canon, organized. JazzCatalog is a chart reader built for working musicians. Browse thousands of standards across every canonical fake book, drop in your own charts, build setlists for the night, and practice with a built-in metronome, MIDI chord recognition, annotations, and YouTube playback — all on your iPad or iPhone. WHAT'S INSIDE • 3,500+ standards. Search the entire jazz canon by title or book. Filter to playable tunes or your bookmarked favorites. • Add your own charts. Drop in any single-song PDF and it joins the catalog right alongside the standards. Or override a tune's book version with your own arrangement — the app will use your PDF for that song while keeping the book for everything else. • Setlists. Build the night in your own order. Tap Next on the bandstand and you move to the next tune in the list, not the next page in the book. • Practice metronome. Visual click with time signatures and accents. Per-song BPM is saved automatically the moment you change it. • MIDI chord display. Plug in a keyboard and the chord you're holding shows on screen — inversions, slashes, and extensions resolved correctly. • Annotations. Mark up charts with pen, marker, or pencil. Use a finger or Apple Pencil. Annotations stay locked to each tune across launches. • YouTube reference tracks. Listen to a canonical recording of any tune while reading the chart. The player floats — drag it anywhere that doesn't cover the staff. • Your library, your way. Import legally-acquired PDFs of full fake books, or drop in single-song charts. Everything stays on your device — no cloud, no account, no subscription. BUILT FOR THE BANDSTAND JazzCatalog isn't a beginner app or a notation editor. It's a tool for the working musician who already plays the music and needs the chart, the chord reference, the click, and the recording all in one place. PRIVACY Your library, bookmarks, custom charts, and setlists stay on your device. There's no account to create. There's nothing to sync.

About

Jazzlore Chords

Features
Read full description

The chords every jazz musician should know, drawn and played. Most chord apps are encyclopedias — thousands of chords, hundreds of variations, an entry for every alteration you'll never use. Jazzlore Chords is the opposite: a focused reference for the chords that actually appear on every page of every real book. The ones you need to recognize on sight, hear in your inner ear, and voice without thinking. Both notations, side by side. Cmaj7 and Cā–³. C-7 and Cm7. We show you both because the jazz world uses both, and pretending otherwise is how students get confused at jam sessions. Audio for every voicing. Tap to hear the chord played cleanly, in a register that lets you sing the changes back. Staff notation. See the chord written out, not just labelled. Reading is part of the practice. Clean, distraction-free interface. Large, legible, dark by default. Made to sit on top of the piano while you work. No accounts, no ads, no tracking, no analytics. The app does one thing — show you the chord, sound the chord, get out of the way. Part of the Jazzlore family of jazz reference apps. Free, open source, ad-free, made for musicians.
