Earnest Jackson here. I’ve spent over 30 years playing and teaching bass — from professional sessions to players who just want to sound better at home.

I put together this short Field Guide so you always have the essentials within reach. It’s designed to live on your phone or tablet and be useful the moment you need it.

What’s inside:

• Chord-scale charts so you know what to play over any chord
• The three core arpeggios every bassist needs (with fingerboard diagrams)
• Clear explanations of how chords are written
• Simple root + 5th patterns for Country, Jazz, Bossa, Mambo, and Reggae
• Gig bag checklist and the key questions to ask before taking a gig

This is not a long method book. It’s a practical reference you can actually use.
