Your first fretted note

Why fret at all

Up to now you’ve only played open strings — three pitches, one per string. To make melodies, you press the long strings against the neck with your left hand to shorten their vibrating length, raising the pitch.

The guembri is fretless — there are no metal frets, just smooth wood. Players use a small set of reference positions they find by ear and memory. The canonical analysis (Vanelli 2017, Sum 2012) maps seven positions per string. We’ll start with five — open, plus four stopped positions (p1, p2, p3, p4) — and grow into p5 and p6 in a later lesson, once these feel natural under the hand.

Five positions on string 1

Pitches shown for the Standard D tuning (low D drone). The spacing here is approximate — exact positions on a fretless neck depend on string length and are settled by ear.

Find p1 by ear

Don’t worry about exact placement yet — get the sound first. Try this:

1. Pluck the open low D (string 1, no left hand).
2. Press the same string against the neck about three fingers’ width below the nut. Pluck.
3. You should hear a clearly higher note — about a whole step up (D → E). If it sounds the same, your finger isn’t pressing hard enough; if it sounds choked, you’re too close to the nut.
4. Slide your finger until that higher note rings clean and steady. That’s p1 for your hand on your instrument.

Repeat for p2, p3, p4 — each one a bit further down the neck, each one a bit higher in pitch. The synth labels are diatonic stand-ins; what matters is that your p1 sounds like a step up, your p2 sounds clearly higher than p1, and so on.

Practice — open and p1 alternating

The exercise below alternates open and p1 on the four beats. Beats 1 and 3 are accented opens (the drone); beats 2 and 4 are softer p1s. Krakeb keeps time underneath.

• Slow it down to 50–60% with the tempo slider while you find your finger placement.
• Mute the krakeb at first if you want silence under your own playing.
• Loop it for a couple of minutes — the goal is consistent, in-tune p1, not speed.

Up next

Once open ↔ p1 feels natural, expand to p2, then p3 and p4. Most Gnawa basslines stay within these five positions for the duration of an entire piece — you already have most of the fingerboard you’ll ever need.

More lessons will build on this: a short melodic phrase, then your first full named piece from the repertoire.
