Every bassist knows the challenge: finding consistency across the vast landscape of the fingerboard.
In his tonebase course Fingerboard Geography Fundamentals, Ali Kian Yazdanfar reveals how the natural harmonics of the instrument can serve as guideposts, helping you navigate shifting, bowing, and intonation with greater precision and awareness.
By exploring the partials — the natural divisions of the string — Yazdanfar shows how each harmonic can become a reference point for both your ear and your bow. He demonstrates how to use these resonances to recenter your sound, align bow placement near the bridge, and even smooth out tense or uneven shifts.
What begins as a simple study in harmonics evolves into a powerful exercise in control, tone production, and musical confidence.
