1) Long-tone principles inside simple one-string melodies

The goal here is to keep the same sound quality you can produce on a single sustained note, but now while the left hand changes pitches. The bow should feel like the “steady engine,” while the fingers simply choose notes. If the tone changes every time you change pitch, treat it as a bow consistency issue first (not a left-hand strength issue).

Task A: One-string “mini-melody” with one bow per note

Choose one string (start on D or A). Use a very simple pitch set that stays on that string only (for example on A string: A–B–C#–B–A, or on D string: D–E–F#–E–D). Keep it slow enough that you can listen.

  • Step 1 (tone target): Play the first note as a long tone (about 4 counts) and memorize the sound you like.
  • Step 2 (same bow, new pitch): Play the melody with one full bow per note (or half bow if full bow is too long). Your only job is to make every note match the first note’s tone quality.
  • Step 3 (bow lane check): After each note, pause with the bow still on the string. Notice whether you drifted toward the fingerboard or toward the bridge. Reset to your chosen lane before the next note.
  • Step 4 (repeat with reversed bowing): If you first started down-bow on the first note, repeat starting up-bow. The melody should sound equally stable either way.

Task B: Two notes per bow (legato connection)

This adds a musical connection without changing the core requirement: stable tone and stable lane.

  • Step 1: Play two melody notes on one bow (e.g., A–B on one down-bow, C#–B on one up-bow, etc.).
  • Step 2: Keep the bow moving continuously through the left-hand change. If the sound “bumps” at the finger change, reduce the left-hand pressure slightly and keep the bow motion calm and uninterrupted.
  • Step 3: Listen for a single, even ribbon of sound. If the second note is suddenly louder or thinner, adjust bow speed slightly rather than changing your contact point.
What you hearMost likely bow causeImmediate fix inside the melody
Pitch change causes a sudden scratchExtra bite at the start of the new fingerKeep bow moving; lighten the start of the new pitch while maintaining the same lane
Second note on the bow is weakerBow speed slows unintentionallyPlan a steady travel rate; imagine “coasting” through the finger change
Tone gets airy mid-bowContact point driftPause, reset lane, repeat slower with a visual check

2) Controlled dynamics while keeping a steady contact point

Dynamics should come from intentional changes in bow speed and weight while the contact point stays stable. If your lane wanders when you play louder or softer, the sound change becomes unpredictable and you lose control of response.

Task A: “Crescendo–diminuendo” on a single note, then inside a melody

  • Step 1 (single note): Choose one note on one string. Play a long bow and gradually get louder for the first half, then gradually softer for the second half. Keep the bow lane visually steady.
  • Step 2 (repeat with opposite bow): Do the same on an up-bow. The dynamic shape should not depend on bow direction.
  • Step 3 (apply to melody): Take the one-string mini-melody from section 1 and shape it: get louder toward the middle note, then softer back to the end. Keep the contact point the same for every note.

Task B: “Terraced dynamics” (two levels only)

This is simpler than a gradual swell and often cleaner for beginners: you switch between two controlled sound levels without changing lane.

  • Step 1: Pick two dynamic levels: soft and medium-loud (avoid extreme loud at first).
  • Step 2: Play your one-string melody with a pattern: soft for two notes, medium-loud for two notes, repeat.
  • Step 3: Check that the louder notes do not pull you closer to the bridge or cause the bow to tilt. If they do, reduce the dynamic difference and rebuild control.
Example pattern (one bow per note):  p  p  mf  mf  p  p  mf  mf

3) Combining string crossings with consistent tone in short patterns

Now the musical task is short patterns that cross strings while keeping the same tone color and volume. The bow should feel like it stays in one “sound world” even as the string changes.

Task A: Two-string neighbor pattern (slow, even notes)

Choose a pair of adjacent strings (D–A or A–E). Use open strings first so you can focus on sound.

  • Step 1: Play four even notes: D–A–D–A (or A–E–A–E). Use the same amount of bow for each note.
  • Step 2: Listen for matching tone on both strings. If one string sounds brighter or harsher, do not “hunt” for a new lane; keep the lane consistent and adjust bow speed/weight slightly to match the tone.
  • Step 3: Add left-hand notes on one of the strings while keeping the crossing pattern (e.g., D(open)–A(1st finger B)–D(open)–A(2nd finger C#)). The bow’s job is still: even tone, even rhythm.

Task B: Short crossing pattern with slurs (two notes per bow)

Slurring across strings tests whether your contact point and bow travel stay organized while the level changes happen smoothly.

  • Step 1: Slur two notes per bow: D–A on one down-bow, D–A on one up-bow.
  • Step 2: Keep the sound continuous through the crossing. If there is a gap, your bow speed likely stopped at the crossing; keep the bow moving and make the level change smaller.
  • Step 3: Repeat with A–D (reverse order). The tone should remain equally stable.
Crossing issue you hearWhat to aim for musicallyAdjustment during the pattern
One string “pops out” louderSame dynamic on both stringsUse slightly less speed on the louder string while keeping lane steady
Crunch at the crossingContinuous sound, no accentSoften the start of the second string; keep bow moving
Thin sound on the upper stringSame core toneAdd a touch more weight (not more pressure) without moving closer to the bridge

4) Articulation basics: gentle starts and clear releases (no crunch)

In these tasks, articulation means how you begin and end each note so the sound speaks cleanly. A “crunch” usually happens when the bow grabs the string too aggressively at the start, or when the bow starts from a tense stop. A clean start is prepared, then released into motion; a clean ending is a controlled stop (or lift) without extra noise.

Task A: Prepared start (silent set → sound)

  • Step 1 (set): Place the bow on the string in your chosen lane. Let the hair make contact without pressing. Feel stable, not heavy.
  • Step 2 (release into motion): Start the bow with a small, smooth movement. The first instant of sound should be clear, not explosive.
  • Step 3 (repeat on different parts of the bow): Try the same prepared start near the frog, middle, and tip. The sound should speak reliably in each place.

Task B: Clear releases (ending notes on purpose)

Many uneven sounds come from “accidental endings” where the bow runs out or the hand collapses. Practice endings as deliberately as beginnings.

  • Step 1: Play a short note (about 1 count). Stop the bow cleanly while staying on the string for a moment of silence.
  • Step 2: Repeat, but this time release the bow by lifting slightly after the stop (only if you can lift without scraping).
  • Step 3: Put this into a one-string melody: each note begins with a prepared start and ends with a clean stop. Keep the rhythm steady so the articulation stays musical rather than fussy.

Task C: Gentle “dah” articulation (not percussive)

Think “dah,” not “tah.” The bow starts with motion first, then the sound blooms immediately. This prevents the common beginner habit of pressing, then yanking.

  • Step 1: On one string, play four quarter notes with the same bow amount each time. Each note: set → move → sound.
  • Step 2: Keep the contact point steady while you articulate. If your lane drifts during repeated starts, slow down and reduce the size of the stroke.
  • Step 3: Apply to a two-string crossing pattern (D–A–D–A). Each note should start cleanly without extra bite, even when changing strings.

Self-assessment rubric (use after each task)

Score each category from 1 to 5. Use short notes to describe what you heard and what you changed.

Category1–2 (needs work)3 (developing)4–5 (reliable)
Straightness of bowBow visibly drifts; sound changes unpredictablyMostly straight with occasional correctionsStays straight without frequent visual checking
Contact point consistencyLane wanders when changing notes/dynamics/crossingsLane is stable in simple tasks, less stable in harder onesLane stays consistent across melody, dynamics, and crossings
Even tone across the bowNoticeable bumps, thinning, or harshness in parts of the bowSome unevenness but improving with attentionTone remains even from frog to tip at chosen dynamic
Intentional adjustment of speed/weight/placementChanges happen accidentally; hard to repeat resultsCan adjust one variable at a time with mixed consistencyCan choose and repeat specific changes to fix tone on purpose

Now answer the exercise about the content:

While playing a one-string mini-melody, the tone changes noticeably every time the left hand changes pitch. What should you treat as the first issue to fix?

You are right! Congratulations, now go to the next page

You missed! Try again.

If tone changes with each pitch change, treat it as a bow consistency issue first. Keep the bow steady like an engine so every note matches the initial long-tone sound, and keep the lane consistent.
