Things to consider when buying a Grand piano:

When buying a used grand piano, thoroughly inspect the instrument's condition, paying close attention to the soundboard, keys, hammers, and strings. Also, consider the piano's history, service record, and whether it's been kept in a suitable environment. Finally, consult with a piano technician to assess the piano's overall condition and potential for future issues before making a purchase.

Here's a more detailed breakdown:

1. Initial Inspection:

• Cosmetic Condition: Check for scratches, dents, or cracks in the finish, as these can indicate how well the piano was cared for.

• Soundboard: Look for cracks or signs of warping in the soundboard, as this can significantly affect the sound quality.

• Keys: Ensure all keys are functional, move smoothly, and produce a clear sound when pressed. Check for chipped, discolored, or missing key coverings.

• Hammers: Examine the hammers for excessive wear or grooving, as this can indicate heavy use.

• Strings: Inspect the strings for rust, corrosion, or damage. Broken or damaged strings can affect the sound quality.

• Tuning Pins: Check that the tuning pins are tight, as loose pins can make it difficult for the piano to hold a tune.

• Pedals: Test all pedals (sustain, soft, and sostenuto if present) to ensure they engage smoothly without squeaking or sticking.

• Rattles and Buzzes: Listen for any unusual noises, especially in the bass notes, as these could indicate underlying issues.

2. Deeper Examination:

• Serial Number: Locate the serial number (usually on the iron plate under the music desk on grand pianos) to determine the piano's age and potentially verify its history.

• Service History: Ask the seller about the piano's maintenance history, including when it was last tuned and if any major repairs have been performed.

• Environmental Conditions: Inquire about where the piano was stored and if it has been exposed to extreme temperatures or humidity, as these can affect its condition.

• Professional Assessment: It is highly recommended to have a piano technician inspect the piano before purchasing, especially if you are not knowledgeable about piano mechanics. According to some online forums, they can provide a thorough assessment of the piano's condition and identify potential problems. 

3. Brand and Model Research:

• Reputation: Research reputable piano brands and models, considering factors like build quality, sound, and resale value.

• Professional Opinion: Consult with piano teachers, technicians, or other musicians for recommendations on suitable brands and models.

4. Budget Considerations:

• Price Range: Be realistic about your budget and research the price range for used grand pianos of similar quality and age.

• Hidden Costs: Factor in potential costs for moving, tuning, and any necessary repairs or refurbishments.

5. Other Factors:

• Playing Experience: Play the piano yourself to assess its touch, responsiveness, and overall sound quality.

• Aesthetics: Consider the piano's appearance and whether it fits your aesthetic preferences.

• Warranty: Check if the seller offers any warranty or guarantee on the piano.

By following these tips and taking your time to thoroughly evaluate a used grand piano, you can find a high-quality instrument that will provide years of musical enjoyment.
