How To Play Cross Harp Second Position On The Diatonic Harmonica
Cross harp, or second position, is the foundational blues harmonica technique that unlocks the expressive, wailing sounds of blues, rock, and country music by playing in a key a fifth above the instrument's stamped key. Mastering this approach requires understanding how to blend standard breath control with draw bends to access the heavily used blues scale and flat seventh intervals.
Essential Gear Setup and Underlying Music Theory for Second Position
Playing cross harp requires a standard diatonic 10-hole Richter-tuned harmonica. Unlike first position (straight harp), which plays in the key stamped on the instrument's cover plate, second position utilizes the lower, draw-heavy end of the instrument to create instant tension and release. This positioning is fundamentally rooted in music theory, specifically the circle of fifths. When you pick up a C major diatonic harmonica, playing in second position places you in the key of G.
- Essential Gear and Tools: A high-quality 10-hole diatonic harmonica in the key of C (for learning G blues), a comfortable neck rack if playing acoustic guitar simultaneously, and a chromatic tuner for pitch accuracy verification.
- Mandatory Prerequisite Knowledge: Basic breath support from the diaphragm, single-note isolation using the tongue-blocking or lip-purling embouchure, and a basic working knowledge of draw bends on holes 2, 3, and 4.
- Execution Benchmarks: Ability to sustain a steady chord on the lower draw notes for three seconds, cleanly isolate single notes without air leakage, and execute a half-step bend on hole 3 with consistent pitch stability.
Step-by-Step Guide to Mastering Cross Harp Second Position
Step 1: Select the Correct Harmonica and Identify the Root Note
To play a blues in the key of G, select a diatonic harmonica stamped with the letter C. The fundamental root note of your new scale is located on hole 2 draw (G), which serves as your home base and resolution point. Take the harmonica, seal your lips firmly around hole 2, and inhale steadily from your diaphragm rather than your chest.
Pro-Tip: If your 2 draw sounds airy or chokes out entirely, drop your jaw slightly, tilt the back of the tongue downward, and ensure you are drawing air deeply from your stomach muscles.
Step 2: Map the Primary Tonic and Dominant Chords
Unlike first position where the 1 blow is your home chord, second position relies on the 2 draw and 3 draw as your primary tonal centers because they outline the G dominant seventh chord (G-B-D-F). Blow softly into holes 1, 2, and 3 simultaneously to produce a C major chord for your backing accompaniment, but immediately pull back to the 2 draw or 3 draw to establish the dominant cross harp tonality. Practice alternating smoothly between the 2 draw and 3 draw to feel the natural cadence of the blues progression.
Step 3: Integrate Draw Bends to Access Missing Scale Tones
Standard major diatonic harmonicas lack certain notes in their middle registers when played straight up and down, which is precisely why cross harp relies heavily on bending techniques. To get the crucial flat seventh note (F) and the minor third (Bb) needed for an authentic blues sound, move to hole 4 draw and lower the pitch by a whole step, or practice the complex multi-step bends on hole 3 draw. Inhale gently while raising the middle of your tongue toward the roof of your mouth, shaping an "ee-oo" vowel sound inside your oral cavity to warp the reed pitch downward.
Warning: Never force a bend by biting down aggressively on the cover plates with your teeth, as excessive pressure will warp the brass reeds and permanently ruin the harmonica tuning.
Step 4: Construct the Second Position Blues Scale
Combine your unbent draw notes with your newly mastered bends to run the quintessential blues scale in second position. Starting from the 2 draw (root), move to the 3 draw bent a whole step, then the 4 blow, 4 draw bent a half-step, 4 draw straight, and finally the 5 draw. Practice running this six-note sequence up and down metronomically until your fingers and breath pattern operate instinctively without conscious visual mapping.

Troubleshooting Common Cross Harp Execution Failures
- Root Cause: The 2 draw note sounds weak, nasal, or flat compared to the surrounding holes.
- Actionable Fix: Relax your lower jaw, drop the floor of your oral cavity to create a larger resonance chamber, and ensure you are drawing air from deep within your diaphragm rather than sucking through pinched lips.
- Root Cause: Hole 3 draw bends drop too far or crack into an unstable warble instead of a clean half-step or whole-step interval.
- Actionable Fix: Use a chromatic tuner app on your smartphone to monitor real-time pitch drop while you articulate subtle shifts in tongue arch shape, treating the tongue like a variable slide whistle.
- Root Cause: Excess saliva builds up in the comb channels, causing reeds to stick and buzz mid-phrase.
- Actionable Fix: Periodically tap the back of the harmonica firmly against the palm of your hand between songs to clear out accumulated moisture, and avoid sugary beverages immediately prior to playing.
Frequently Asked Questions
What key harmonica do I need for cross harp in the key of A?
To play cross harp in the key of A, you must use a D major diatonic harmonica. The second position root note will be located on the 2 draw (A), allowing you to access the correct dominant seventh chord structure and blues scale for an A backing track.
Why is second position called cross harp?
The term originates from traditional folk and blues terminology because the musical key of the song crosses over and differs from the key stamped on the manufacturer's box. Instead of playing in the direct key of the instrument (straight harp), you cross over into the fifth interval above it.
Can I play minor blues songs using second position?
Yes, second position is frequently used for minor blues tunes, particularly by utilizing the dominant seventh characteristics of the scale to create tension against minor backing progressions. However, for strict minor modality, many players eventually transition to third position.
How long does it take to learn how to bend notes in second position?
Most players achieve a basic, stable bend within two to four weeks of consistent daily practice focusing on embouchure adjustment and breath support. Developing clean, pitch-accurate bends across all target holes typically requires several months of dedicated tone training.
Elevate your blues improvisations today by grabbing a C harp, anchoring your breath to the 2 draw, and exploring the expressive world of cross harp second position.
