Secundal intervals, which are intervals of a second (either major or minor), offer a unique way to create interesting and modern voicings in both guitar and piano playing. These intervals are often used in jazz, contemporary, and experimental music to add tension, color, and complexity to harmonic progressions.
Understanding Secundal Intervals
A secundal interval is the distance between two notes that are a second apart. In Western music, these can be:
- Major second: two semitones (e.g., C to D)
- Minor second: one semitone (e.g., C to C#)
In harmony, these intervals create a sense of dissonance, making them ideal for building tension or color in chords.
Using Secundal Intervals in Voicings
In guitar and piano, secundal intervals can be combined to form chords that sound modern and fresh. Here are some tips:
- Stack secundal intervals: Play two seconds stacked to form a chord, such as a major second and minor second together.
- Create clusters: Play adjacent notes of a scale or chord to produce a cluster of seconds, adding dissonance.
- Combine with other intervals: Mix secundal intervals with thirds or fifths for richer voicings.
Practical Examples
On guitar, you might play a voicing using the notes C, D, and E together to create a lush, modern sound. On piano, try stacking D and E above a C bass to form a chord rich in seconds. Experiment with moving these intervals up and down the neck or keyboard to find unique sounds.
Example Chord Shapes
- Guitar: Play a C major chord (C, E, G) and add a D note on top to emphasize the second interval.
- Piano: Play C, D, and E together for a cluster voicing.
Incorporate secundal intervals into your practice to develop a modern harmonic vocabulary and create more colorful, expressive voicings in your playing.
