How the Right Arm Adapts Across the Four Strings
Your bow arm is not “one fixed shape.” It is a moving system where the elbow height and forearm angle adjust to reach each string while the shoulder stays heavy and down and the wrist remains supple. The goal is to change strings by rotating and lifting the arm as a unit, not by hiking the shoulder or twisting the wrist.
String-by-string map: elbow level and forearm angle
Use these descriptions as a starting point. Your exact angles will vary with your arm length and instrument setup, but the relationships stay the same.
| String | Elbow height (relative) | Forearm angle & feeling | Common sensation |
|---|---|---|---|
| G | Lowest | Forearm slightly more “under” the bow; arm hangs more | Heavier string; allow natural arm weight |
| D | Low–middle | Forearm a bit more level; easy hinge at elbow | Often feels like the “neutral” string |
| A | Middle–high | Forearm more level with the bow; elbow opens slightly | Keep shoulder quiet while arm rises |
| E | Highest | Forearm more “above” the bow; elbow lifted but not tense | Light string; avoid pressing or stiffening |
Key rule: as you move from G to E, the elbow rises gradually and the forearm rotates so the bow hair stays flat and stable on the string. The shoulder should not creep upward to “help.”
Shoulders down, wrist supple: what that actually means
- Shoulders down: the collarbone area stays wide; the right shoulder feels heavy, not pulled up toward the ear. If you feel neck tension, you are likely lifting the shoulder.
- Wrist supple: the wrist follows the bow direction with small, natural motion. It is neither locked straight nor dramatically bent. Think “alive and springy,” not “posed.”
Straight Bow Path: Visual and Tactile Cues
A straight bow path means the bow travels perpendicular to the string and stays parallel to the bridge throughout the stroke. This keeps contact consistent, helps tone, and prevents accidental string crossings.
Visual cues (what to look for)
- Bow parallel to bridge: check the distance between bow and bridge at the frog, middle, and tip. It should look the same.
- Bow stays on one “lane”: imagine a narrow track between bridge and fingerboard; the bow should not drift toward either edge.
- Elbow leads the lane change: if the bow drifts, it is often because the elbow height didn’t match the string.
Tactile and sound cues (what to feel/hear)
- Even resistance: the string should feel consistently “grippy,” not suddenly slippery or overly resistant.
- Stable contact point: you feel the same part of the bow hair contacting the string, without rolling to the edge.
- Even sound: a steady tone with no sudden thinning (often too close to fingerboard) or crunching (often too close to bridge with too much pressure).

1) Silent bow placement (no sound)
Goal: place the bow on the chosen string with the correct arm level and a relaxed shoulder.
- Choose one string (start with D or A).
- Set the bow on the string halfway between bridge and fingerboard.
- Before moving, check: shoulder heavy/down, elbow at the correct level for that string, wrist not collapsed inward or pushed outward.
- Without moving the bow, gently “rock” your arm level to hover over the neighboring string (D↔A, A↔E, D↔G) and return—still silent. This teaches that string changes come from arm level, not wrist twisting.
Self-check: if the bow slides or scratches during placement, reduce pressure and focus on quiet contact.
2) Open-string slow bows (long strokes)
Goal: keep the bow parallel to the bridge for the full travel.
- Start at the middle of the bow on an open string.
- Play a slow down-bow for 4–8 counts, then a slow up-bow for 4–8 counts.
- Watch the bow-bridge relationship: if the bow drifts, pause, reset the lane, and continue.
- Repeat on each string, adjusting elbow height each time before you start moving.
Tip: if the bow wants to curve, think of the forearm opening/closing at the elbow while the upper arm supports the correct height for that string.
3) Short strokes (small, controlled motion)
Goal: maintain straightness and contact during quick direction changes.
- Stay on one string (start with D).
- Use short strokes in the middle of the bow: 1–2 inches (2–5 cm).
- Keep the bow hair stable on the string; avoid rolling the stick toward/away from you.
- Listen for consistency: each short stroke should match the next in tone and volume.
Progression idea: do 8 short strokes on D, then 8 on A, then back to D—adjust elbow level before each set.
Mistakes to Avoid (and Quick Resets)
1) Raising the right shoulder
What it causes: tension, shaky bow changes, and difficulty reaching the E string cleanly.
Quick reset: stop the bow, let the right arm hang for one breath, then place the bow again while keeping the shoulder heavy. Resume with a slow stroke.
2) Bowing too close to the fingerboard or too close to the bridge (without control)
What it causes: near the fingerboard the sound can become airy and unfocused; near the bridge it can become harsh or crunchy if pressure and speed are not balanced.
Quick reset: return to the “middle lane” (roughly halfway between bridge and fingerboard). Play two slow bows focusing on even sound, then gradually explore slightly closer to bridge or fingerboard only if the tone stays stable.
3) Over-bending the wrist (collapsing or “breaking” the line)
What it causes: wobbly contact, uneven tone, and difficulty keeping the bow straight—especially at direction changes.
Quick reset: pause at the middle of the bow, gently straighten the wrist to a neutral, springy shape (not rigid), then restart with short strokes that are small enough to control.
4) Drifting bow path (not parallel to the bridge)
What it causes: accidental string crossings, inconsistent tone, and scratchiness at random points in the stroke.
Quick reset: freeze the bow where it is, visually realign it parallel to the bridge, then continue for just 2 inches (5 cm) to “retrain” the lane before attempting a full stroke again.
5) Changing strings by twisting the wrist instead of adjusting elbow level
What it causes: unstable contact and a feeling of “missing” the string.
Quick reset: practice silent string changes: place on D, lift to A by raising elbow slightly, return to D—no wrist twist, no shoulder lift. Then add sound with slow bows.
