* **Polyester Cord:** More resistant to UV degradation than nylon. A good all-around choice.
* **Braided Fishing Line:** Incredibly strong and UV-resistant, but can be more difficult to work with.
* **Wire:** (For supporting heavier tubes or bars) Use stainless steel or copper wire for corrosion resistance.
* **Striker (Clapper/Sail):**
* **Wood:** Provides a soft, mellow strike.
* **Metal:** Creates a brighter, more resonant strike.
* **Stone/Glass:** Offers a unique and textured sound.
* **Sail (Wind Catcher):**
* **Wood:** Provides a natural look and can be easily customized with paint or carvings.
* **Metal:** Durable and reflects light, adding visual interest.
* **Acrylic:** Lightweight and available in various colors.
### 3. Determining Tube Lengths and Tuning
The heart of a wind chime lies in its tuning. The length of the tubes (or bars) determines the pitch of the notes they produce. To achieve a harmonious sound, you’ll need to calculate the correct lengths for your chosen scale.
* **Understanding Musical Scales:** A musical scale is a sequence of notes arranged in a specific order. Common scales for wind chimes include:
* **Pentatonic Scale:** A five-note scale that sounds harmonious and pleasing to the ear. It’s a great choice for beginners.
* **Major Scale:** A seven-note scale that sounds bright and cheerful.
* **Minor Scale:** A seven-note scale that sounds more melancholic or reflective.
* **Calculating Tube Lengths:** The formula for calculating the length of a tube to produce a specific frequency (note) is:
* `L = (v / 2f) * K`
Where:
* `L` = Length of the tube (in inches or centimeters)
* `v` = Speed of sound in the material (inches/second or cm/second). This value varies depending on the material. For aluminum, it’s approximately 200,400 inches/second (or 509016 cm/second).
* `f` = Frequency of the desired note (in Hertz).
* `K` = A correction factor that accounts for the end correction (the effect of the open ends of the tube on the frequency). This value is approximately 0.96 for tubes open at both ends.
* **Finding Frequencies (Hertz):** You can find the frequencies of notes online using a frequency chart or a musical instrument tuner. For example, A4 (the A above middle C) has a frequency of 440 Hz.
* **Using Online Calculators:** Several online wind chime tuning calculators simplify the process. Simply enter the desired scale and material, and the calculator will provide the corresponding tube lengths.
**Example: Tuning to a Pentatonic Scale in C**
A common and beautiful scale for wind chimes is the C pentatonic scale. The notes are C, D, E, G, and A. Let’s say we want to calculate the length of an aluminum tube for the note C5 (523.25 Hz).
1. `v` = 200,400 inches/second (speed of sound in aluminum)
2. `f` = 523.25 Hz (frequency of C5)
3. `K` = 0.96 (correction factor)
`L = (200,400 / (2 * 523.25)) * 0.96`
`L = (200,400 / 1046.5) * 0.96`
`L = 191.49 * 0.96`
`L = 183.83 inches`
So, the length of the aluminum tube for C5 would be approximately 183.83 inches. Repeat this calculation for each note in your chosen scale.
**Important Considerations:**
* **Units:** Ensure all measurements are in the same units (inches or centimeters) throughout the calculation.
* **Accuracy:** Precision is crucial for accurate tuning. Use a precise measuring tool and cut the tubes as accurately as possible.
* **Experimentation:** Don’t be afraid to experiment with different lengths to fine-tune the sound to your liking. Slight variations in length can create unique and interesting harmonies.
## Building Your Wind Chime: Step-by-Step Instructions
### 1. Gathering Your Tools and Materials
Before you begin, gather all the necessary tools and materials:
* **Tubes/Bars:** Cut to the calculated lengths.
* **Suspension Platform:** Cut and finished (if using wood).
* **Suspension Cord:** Sufficient length for hanging the tubes and platform.
* **Striker:** Chosen material and shape.
* **Sail:** Chosen material and shape.
* **Drill:** With appropriate drill bits for your materials.
* **Measuring Tape/Ruler:** For accurate measurements.
* **Saw:** For cutting tubes and platform (if necessary).
* **Sandpaper:** For smoothing rough edges.
* **Scissors/Knife:** For cutting cord.
* **Pliers:** For working with wire (if using).
* **Safety Glasses:** To protect your eyes.
* **Gloves:** To protect your hands.
### 2. Preparing the Tubes/Bars
* **Cutting:** Cut the tubes or bars to the calculated lengths using a saw or pipe cutter. Ensure the cuts are clean and straight.
* **Deburring:** Use a deburring tool or sandpaper to remove any sharp edges or burrs from the cut ends. This will prevent the cord from fraying and improve the sound quality.
* **Drilling:** Drill a hole near the top of each tube for suspending it from the platform. The size of the hole should be slightly larger than the diameter of your suspension cord. Consider the node point for drilling. Node point is located approximately 22.4% from either end of the tube.
### 3. Preparing the Suspension Platform
* **Cutting and Shaping:** Cut the platform to the desired size and shape. You can use a circular saw, jigsaw, or hand saw.
* **Sanding:** Sand the edges and surfaces of the platform to create a smooth finish.
* **Finishing:** If using wood, apply a weather-resistant finish such as paint, stain, or varnish. This will protect the wood from the elements and extend its lifespan.
* **Drilling:** Drill holes around the perimeter of the platform for suspending the tubes. The number of holes will depend on the number of tubes you are using. Drill a central hole for hanging the entire wind chime.
### 4. Assembling the Wind Chime
* **Suspending the Tubes:** Thread the suspension cord through the hole in each tube and tie a knot to secure it. Adjust the length of the cord so that all the tubes hang at the same level below the platform.
* **Attaching the Tubes to the Platform:** Thread the other end of the suspension cord through the corresponding hole in the platform and tie a knot to secure it. Ensure the knots are tight and secure.
* **Attaching the Striker:** Suspend the striker from the center of the platform using a separate piece of cord. The striker should hang freely and be able to strike the tubes when the wind blows. Adjust the length of the cord so that the striker hangs at the desired height.
* **Attaching the Sail:** Attach the sail to the bottom of the striker using a cord or wire. The sail will catch the wind and cause the striker to move.
* **Hanging the Wind Chime:** Thread a cord through the central hole in the platform and tie a knot to create a loop for hanging the wind chime.
## Tuning Your Wind Chime: Fine-Tuning for Perfect Harmony
Even with precise calculations, minor adjustments may be necessary to achieve perfect tuning. Here are some tips for fine-tuning your wind chime:
* **Adjusting Tube Lengths:** If a tube is slightly flat (too low in pitch), you can shorten it slightly by cutting off a small amount from the bottom. If a tube is slightly sharp (too high in pitch), you can lengthen it by adding a small weight to the bottom (e.g., a metal washer or a small dab of epoxy).
* **Adjusting Striker Position:** The position of the striker can affect the sound of the chime. Experiment with different striker heights to find the sweet spot where the tubes produce the clearest and most resonant tones.
* **Adjusting Suspension Cord Lengths:** The length of the suspension cords can also affect the tuning. Try adjusting the lengths slightly to fine-tune the sound.
* **Listen Carefully:** The best way to tune your wind chime is to listen carefully and make adjustments until you are satisfied with the sound. Use a musical instrument tuner as a reference, but ultimately, trust your ears.
