Keen Bass: The Mindful Bassist's Journey redefines ​the learning experience for double bassists. ​Under the guidance of Marcos Machado, we offer ​unique, standalone 5-8 page digital booklets released ​every Monday. These delve into specific bass ​concepts or excerpts crafted to enhance your practice ​with consistency and variety. Keen Bass distinguishes ​itself by providing the flexibility to purchase releases anytime, allowing you to tailor your learning ​experience to your pace and interests, free from the ​constraints of a subscription model.
