In JJazzLab "rhythm" usually means a music style, like pop or bossa-nova.
🎵 With JJazzLab you quickly create backing tracks for any song, even complex ones. It’s a jam buddy to have fun practicing at home or learn new stuff. It’s also a great tool for teaching or early-stage composing.
🎷 JJazzLab is designed to make non-boring backing tracks, backing tracks with variety, rhythmic accents and dynamics. You can start a solo slowly and gradually build up the atmosphere!
💻 JJazzLab is open-source with an open architecture: developers can easily add new features and new music generation capabilities.
Install and run JJazzLab, then :
Load an example song file : menu File/Open Songs... and select ExampleFiles/BluesMinor.sng
Press the Play button : you should hear the backing track -if not, check the Midi Out device in menu Tools/Options
Start editing the song using the editors and hear how it impacts the generated backing track.
Watch this 60 seconds video tutorial for a quick start.
Introduce dynamics in just a few clicks:
mute the guitar in the intro
add a break at the end of the 2nd verse
add congas from the 3rd verse
boost intensity and slightly increase tempo at the end
add anticipated chords
simplify the piano on the first verse
Export backing track to Midi or audio
Play transposed (for sax, etc.)
Use Midi remote commands to control playback
Add annotations/lyrics to bars
Edit multiple songs, copy & paste between them
Print chord leadsheet and song structure
Import files from Band-In-A-Box / Text ("|A7 D7 | Gm7 C7|") / MusicXML / Impro-Visor files
Easy Reader window: shows only the playing chords (and annotations/lyrics) with a large font
Chord inspector: shows selected chord symbol notes and scales (piano, guitar diagrams, score)
Arranger keyboard mode: control backing track in (pseudo) real-time via a Midi keyboard
