Top 10 Questions for Piano Maker Interview

1. Describe the process of tuning a piano.

• Inspect the piano to assess its condition and identify any potential problems.
• Set up the tuning equipment, including a tuning fork or electronic tuner.
• Tune the A4 string to the desired pitch (usually 440 Hz).
• Use the A4 string as a reference to tune the remaining strings in each octave.
• Check the tuning stability by playing chords and listening for any dissonance.
• Make adjustments as necessary to ensure accurate tuning.

2. What are the different types of piano strings and how do they affect the sound?

Types of Piano Strings

• Treble Strings: Made of high-carbon steel, these strings are thin and short, producing bright and clear tones.
• Bass Strings: Made of thicker, low-carbon steel, these strings are longer and produce deeper and more resonant tones.
• Winding Wire: Copper or aluminum wire wrapped around the bass strings to increase their mass and lower their pitch.

Effects on Sound

• The thickness and tension of the strings determine the pitch and volume.
• The material and winding of the strings influence the tone quality and sustain.
• Proper string selection and installation are crucial for achieving the desired sound.

3. How do you repair a cracked soundboard?

• Assess the extent of the crack and determine the best repair method.
• Clean the cracked area and remove any loose wood.
• Apply a thin layer of epoxy or other appropriate adhesive to the crack.
• Clamp the crack together and apply pressure to ensure proper bonding.
• Once the adhesive has set, reinforce the repair with clamps or braces.
• Sand the repaired area and apply a finish to match the surrounding wood.

4. What are the common causes of piano key sticking?

• Accumulation of dirt and debris: Dust, food particles, and other debris can accumulate under the keys, causing them to stick.
• Humidity and moisture: Changes in humidity can affect the wooden components, causing them to swell and stick.
• Improper lubrication: Lack of lubrication can increase friction and prevent keys from moving smoothly.
• Damaged or worn parts: Broken or worn springs, hammers, or other internal components can contribute to key sticking.

5. How do you adjust the action of a piano?

• Let-off: Adjusting the let-off affects the point at which the hammers release from the strings.
• Down-weight: Adjusting the down-weight determines the amount of force required to depress a key.
• Key dip: Adjusting the key dip controls the depth to which a key can be depressed.
• Lost motion: Adjusting the lost motion reduces the amount of slack in the action, improving responsiveness.
• Regulation: Properly regulating the action ensures that all keys play evenly and at the same volume.

6. What are the different types of piano hammers and how do they affect the sound?

Types of Piano Hammers

• Grand Piano Hammers: Made of layers of felt, these hammers are large and heavy, producing a rich and resonant sound.
• Upright Piano Hammers: Smaller and lighter than grand piano hammers, these hammers are typically made of layers of felt with a wooden core.
• Plastic Composite Hammers: Made of a durable plastic material, these hammers offer a bright and consistent sound.

Effects on Sound

• The hardness and shape of the hammer head determine the articulation and brilliance of the sound.
• The weight and size of the hammer affect the volume and sustain.
• The choice of hammer type is critical for achieving the desired tonal characteristics.

7. Describe the process of rebuilding a piano.

• Disassemble the piano: Remove all the major components, including the keys, action, soundboard, and strings.
• Repair or replace damaged parts: Address any structural issues, cracks, or worn components.
• Reassemble the piano: Put the components back together, ensuring proper alignment and functionality.
• Tune and regulate the piano: Adjust the action, tension, and tuning to achieve optimal performance.
• Voicing and finishing: Adjust the soundboard and hammers to produce the desired tone and appearance.

8. What are some advanced techniques used in piano making?

• Voicing: Manipulating the soundboard, hammers, and strings to create a specific tonal quality.
• Inharmonicity: Tuning the piano strings slightly out of perfect tune to compensate for natural sound phenomena.
• Scaling: Designing the dimensions and materials of the soundboard and strings to optimize tone and sustain.
• Splicing: Joining multiple pieces of wood to create a single component, such as the case or soundboard.
• Laminating: Bonding multiple layers of wood together to create a stronger and more stable structure.

9. Describe some recent innovations in piano technology.

• Digital pianos: Electronic instruments that simulate the sound and feel of an acoustic piano.
• MIDI pianos: Pianos that can connect to computers and other devices for recording, composition, and playback.
• Silent pianos: Pianos that allow players to practice privately using headphones.
• Self-tuning pianos: Pianos with built-in tuning systems that automatically adjust the strings.
• Carbon fiber soundboards: Soundboards made of lightweight and durable carbon fiber, providing enhanced sustain and projection.

10. What are the ethical considerations in piano making?

• Sustainable wood sourcing: Ensuring the use of wood from responsible and environmentally sustainable sources.
• Fair labor practices: Adherence to ethical employment practices, including fair wages and working conditions.
• Preservation of historical instruments: Respecting the value and preserving the integrity of vintage and antique pianos.
• Proper disposal of waste: Responsible disposal of materials, including wood scraps and chemical waste.
• Transparency and communication: Open and honest communication with customers about the materials and processes used in piano making.
