Built for accomplished bassists, Jazz Bass / 60 turns one focused hour a day into advanced upright mastery. Work through 60 days of quarter-note authority, guide-tone and chromatic routing, elastic time, solo grammar, modal and odd forms, and recorded trio leadership. Read VexFlow bass-clef notation; hear locally bundled real Meatbass pizzicato double-bass recordings with two dynamics; explore 60 playable walking and solo devices, 24 score cells, the original 32-bar study Blue Lantern and three complete original forms. Isolate the core line or ornaments, loop at custom tempo, sync progress to a signed-in VibePlat account or save as a guest in-browser, and use an English, Chinese, Japanese or Spanish interface plus a printable ten-page workbook.
