The Essence of the Open Bottom Design
At the heart of the open bottom hand drum design lies its defining characteristic: the absence of a closed back or resonating chamber. Unlike its closed-shell counterparts, like congas or bongos, the open bottom allows for a free flow of air, significantly impacting the drum’s sonic profile. This design choice, while seemingly simple, unlocks a world of tonal possibilities.
The primary effect of this open construction is enhanced resonance. The sound waves generated by striking the drumhead can freely radiate outwards, enriching the sustain and creating a warmer, more complex sound. This differs significantly from drums with enclosed shells, where the sound is somewhat trapped within the cavity. This inherent difference makes the open bottom hand drum design a favored choice for those seeking instruments with a deep, resonant quality.
Imagine the feeling of a wave crashing on the shore. The resonance of the open bottom mirrors this, allowing the vibrations to flow freely and create a long, sustained sound. This contrasts sharply with the more focused and punchy sounds often associated with closed-shell drums, which offer a more immediate attack and decay. The open bottom hand drum design offers a richer, more complex tapestry of sound that is appealing to musicians across genres. The result is an instrument that breathes, vibrates, and communicates with the player and the surrounding environment in a unique way.
Crafting the Instrument: Design Elements and Construction
The creation of an open bottom hand drum design involves careful consideration of several key elements. From the shape and material of the shell to the type of drumhead and tensioning system, each component plays a crucial role in the instrument’s final sound and playability.
Shell/Body
The body or shell of the open bottom hand drum design is a crucial element. While cylindrical shapes are common, conical, and even hourglass forms can be found. The chosen shape will subtly affect the drum’s resonance and projection.
The materials used for the shell significantly affect the drum’s tone. Wood is a favored choice due to its warm resonance and natural feel. Different types of wood (e.g., mahogany, maple, oak) have unique sonic signatures. Mahogany is known for its deep, resonant tones, while maple often offers brighter, more focused sounds. The thickness of the shell also plays a role, with thicker shells typically producing a more focused and sustained sound.
Fiberglass is another popular option, offering durability and resistance to environmental factors such as humidity and temperature changes. Fiberglass drums often have a brighter sound than wood drums. The choice between wood and fiberglass, like the choice of shape, is a balance of sound, budget, and intended use.
Drumhead
The drumhead, the very surface we strike to make music, is a vital component in the open bottom hand drum design. Heads are available in two primary categories: natural and synthetic.
Natural drumheads, typically made from animal hides like goat, calf, or other skins, offer a warm, organic sound with rich overtones. The character of the skin also influences the sound: thicker skins often produce deeper tones, while thinner skins tend to be brighter. However, natural heads are susceptible to changes in humidity and temperature, and require more careful maintenance.
Synthetic drumheads, primarily made of materials like mylar or Remo Fiberskyn, offer greater consistency and durability. They are less sensitive to environmental changes and provide a more predictable sound, which can be advantageous in different performance settings. Synthetic heads are also available in a wider range of thicknesses and finishes, offering a variety of tonal options.
Tuning and Tensioning
The method of attaching and tensioning the drumhead is also critical. There are a few main approaches to attaching and tuning drumheads:
Rope tuning is a traditional method, often seen on djembe drums. It involves a system of ropes and knots to apply tension to the head. Rope tuning allows for precise adjustments but can be time-consuming.
Lug tuning, the more common approach, uses metal lugs attached to the shell, with bolts to tighten the head. This system allows for more convenient and precise tuning, and often provides a more stable tuning environment.
Each tensioning system will have a different impact on the sound and playing of the open bottom hand drum design. It’s worth exploring which will provide you with the best tone and the easiest playability.
The Sonic Landscape and the Art of Playing
The open bottom hand drum design’s defining characteristic, the open bottom itself, plays a significant role in shaping its sound.
Resonance and Tonal Qualities
The resonance is a key element. The absence of a closed back allows the sound waves to expand freely, creating a rich, full tone with excellent sustain. The open bottom enhances the projection of the sound, making the drum audible in a wide range of settings.
The tonal qualities of the drum are highly dependent on the shell and drumhead materials, as discussed earlier. However, the openness of the design ensures that the instrument offers a broad range of overtones and a warm, enveloping sound that invites musical exploration.
Playing Techniques
The versatility of an open bottom hand drum design is evident in its diverse playing techniques. The ability to produce different timbres and rhythms is essential for expressive and interesting music.
Basic strokes involve striking the head with the hands. The position of the hand on the head determines the sound. A strike near the center often produces a deep, resonant tone, while striking near the edge creates a sharper, more articulate sound.
The use of slaps, open tones, and other techniques allow the player to generate complex rhythms and musical phrases. Muffling and dampening the head with the hands or fingers can also be used to control the sound.
The musical applications of the open bottom hand drum design are wide-ranging. It is used in many music genres, including but not limited to: traditional music, world music, contemporary compositions, and drum circles.
Customizing Your Drum: Exploring the Possibilities
For those drawn to the craft, building or customizing an open bottom hand drum design can be a rewarding journey. While building from scratch can be a complex undertaking, there are resources and guides available for aspiring drum makers.
Materials and tools include the shell, drumhead, and tensioning system. Tools may include a saw, sanding tools, clamps, and potentially a drill. There are many pre-made shells available to simplify the building process.
Aesthetic Customization
Customization offers endless opportunities for individual expression.
One key area is the finish of the shell. This determines not only the aesthetic appearance of the drum but also helps to protect it. Staining, painting, and varnishing can provide a personalized appearance.
Adding decorations, such as carvings, inlays, or unique artwork, allows the player to turn the drum into a personal art piece. This personalized instrument adds a unique touch to any performance.
In Conclusion: Sound, Design, and Connection
In exploring the open bottom hand drum design, we discover an instrument where design and sound are inextricably linked. The absence of a closed back contributes to the drum’s unique resonance, warmth, and expressive potential. From the selection of materials to the playing techniques, the open bottom hand drum design offers a rich musical landscape.
