While open strings have a unique timbre, playing in 3rd and 4th positions on a double bass offers advantages like a more even and balanced tone, consistent control, and the ability to play patterns without relying on open strings.
Here's a more detailed breakdown:
Advantages of Playing in 3rd and 4th Position:
Even and Balanced Tone:
Playing closed notes (not on open strings) can create a more consistent and balanced tone, which is especially important in orchestral settings or when playing in a bass section.
Consistent Control:
Focusing on patterns within a 4-fret span helps develop consistent control of notes under your left hand.
Learning Movable Patterns:
Understanding the "closed position" or "box" shapes of scales and patterns, without relying on open strings, helps you learn movable patterns and abstract musical ideas.
Reduced Left-Hand Movement:
Playing patterns within a smaller fret span can reduce the amount of left-hand movement needed, leading to more efficient playing.
Thicker, Less Trebley Sound:
Closed strings generally produce a thicker, less trebley sound, which can be desirable in certain musical contexts.
Advantages of Using Open Strings:
Unique Timbre:
Open strings have a distinct sound and timbre that can be used to create specific musical effects.
Bounce Point for Shifts:
Open strings can serve as a "bounce point" for shifting left-hand position, making it easier to transition between different areas of the fingerboard.
Expanded Note Possibilities:
Using open strings expands your note possibilities and allows for a wider range of musical expression.
Specific Genres:
Open strings are often preferred in certain genres, such as Irish, English, or Scottish folk music (which is rooted in the Baroque).
Easier for Beginners:
For some, open strings can be easier to learn and play, particularly for beginners.
Ultimately, the best approach depends on the specific musical context, the desired sound, and the individual player's preferences. As Double Bass HQ notes, it's important to understand the nuances of both open strings and closed positions and use them strategically to achieve the desired musical effect.
