Guitar Sequence Advanced Practice - Third Sequence
What is Third Sequence?
Third sequence is a practice method based on scales that connects notes by skipping one note each time. Simply put, it's "playing every other note."
Compared to the previous second sequence (connecting adjacent notes), third sequence produces completely different melodic effects and harmonic colors through interval leaps.
Auditory Characteristics of Third Sequence
Second sequence (e.g., do-re-mi-fa) has smooth and flowing interval connections but is relatively conservative. Third sequence (e.g., do-mi-re-fa) creates the following auditory features due to interval leaps:
- Strong melodic leap sensation: Large interval spans create more melodic起伏
- Clearer harmonic implications: Third intervals naturally suggest chord structures
- Stronger rhythmic drive: Leaping intervals create stronger rhythmic tension
- More prominent modern feel: Widely used in modern music like pop and jazz
Third Sequence Practice Examples
Using the C major natural scale as an example, here are common third sequence patterns:
Ascending Pattern (1324 Type)
- do-mi-re-fa(1324)
- mi-sol-fa-la(3546)
- sol-si-la-do(5761)
- si-re-do-mi(7213)
Descending Pattern (2716 Type)
- re-si-do-la(2716)
- si-sol-la-fa(7564)
- sol-mi-fa-re(5342)
- mi-do-re-si(3127)
C Major Natural Scale Practice Example
C major natural scale: C D E F G A B C (do re mi fa sol la si do)
A-Shape Fingering
Starting from the 5th string, 3rd fret (C note):
G-Shape Fingering
Starting from the 3rd string, 5th fret (C note):
Why is This Sequence Suitable for Solos?
Third sequence has clear advantages in improvisation:
Strong Melodic Memorability
Leaping interval combinations are easier for listeners to remember, making them suitable as thematic motifs in solos.
Clear Harmonic Support
Third intervals naturally correspond to chord tones (root-third, third-fifth, etc.), creating very harmonious sounds when played against corresponding chord backgrounds.
Great Development Potential
Can expand from thirds to larger intervals like fifths, sevenths, etc., providing more possibilities for solo development.
Practice Methods
Step-by-Step Practice Suggestions
- Master single group: First practice do-mi-re-fa(1324)
- Connection practice: After mastering, connect mi-sol-fa-la(3546)
- Complete cycle: Link all four ascending patterns for practice
- Combine ascending and descending: Finally practice connecting ascending and descending patterns
Using Eggfish Metronome
- Starting BPM: 35-40 (third leaps require more preparation time)
- Target BPM: 60-65
- Acceleration interval: Increase 5 BPM every 8 cycles
- Focus: Ensure accuracy of leaping intervals
Practice Key Points
- Interval accuracy: Third intervals must be precise, avoid being too high or low
- Rhythm stability: Rhythm tends to become unstable during leaps, pay special attention
- Dynamic consistency: Maintain consistent dynamics between leaping and stepwise intervals
- Finger preparation: Left hand should prepare for leaps in advance to reduce movement time
Common Problems
- Q: Easy to press wrong frets during third leaps? A: Practice slowly, watch left hand movement, build positional memory
- Q: Unsteady transitions between ascending and descending? A: Practice transition points separately, repeatedly train connection movements
- Q: Intervals become inaccurate when speed increases? A: Return to accurate speed and practice again, don't rush acceleration
Practical Application Suggestions
In C Major Chord Progressions
- C chord: Can play do-mi-re-fa (emphasizing chord tones)
- F chord: Can play fa-la-sol-si (corresponding to chord structure)
- G chord: Can play sol-si-la-re (creating tension and resolution)
As Solo Phrases
- Can be used as phrase openings to create strong impressions
- Can be used as development sections to push music forward
- Can be used as ending parts to reinforce sense of conclusion
Conclusion
Third sequence is a very practical technique in guitar performance. It offers both practice value and directly enhances solo expression. Although initial practice requires adapting to leaping intervals, mastering it adds important expressive means to your performance.
Recommended daily practice: 15-20 minutes. After two weeks, you'll find this sequence naturally integrating into your performance vocabulary.
