- Patterns of general wear and tear
These cosmetic issues might also point to underlying problems that need attention.
Inspect the Surface and Finish
Pay attention to the piano’s finish to assess its overall condition. Look for:
- Signs of veneer repairs or areas where the veneer is damaged
- Irregularities in the finish that could indicate exposure to moisture or frequent use
If you notice any major damage or inconsistencies, it’s a good idea to schedule an evaluation with the experts at Cooper Piano.
Step 3: Check Keys and Action
Now, it’s time to examine the keyboard and action mechanism to determine how well the piano performs. According to experts at Cooper Piano, how the keys respond can reveal a lot about the instrument’s overall condition.
Test Each Key
Press each of the 88 keys one by one. Make sure they return to their original position quickly and produce a consistent, clear tone. You can also play scales to get a better sense of how responsive the keys are. Pay attention to how the keys feel under your fingers – this can help you spot early signs of wear.
Look for Key Damage
Inspect the keys closely for:
- Discoloration: White keys that have yellowed or show uneven coloring could point to age or sun damage.
- Physical Damage: Check for chips, cracks, or breaks along the edges of the keys.
- Misalignment: Keys should be evenly spaced and level across the keyboard.
If you notice inconsistent key responses or multiple signs of damage, consider having the piano evaluated by a professional. Also, while testing the keys, listen carefully for unusual sounds that might indicate issues with the action mechanism. A thorough check of the keys and action is a key part of assessing the piano’s overall condition.
Step 4: Listen to Sound Quality
Once you’ve checked the keys and action, it’s time to focus on how the piano sounds. Experts at Cooper Piano suggest carefully listening to individual notes and chords to assess the instrument’s tonal qualities.
Check Sound Balance
Play across the entire keyboard, from the deep bass notes to the high soprano range. Listen for a consistent tone and volume, and ensure the transitions between registers are smooth.
Watch for Issues
Pay attention to any unusual sounds, such as:
- Buzzing noises, which might indicate loose or damaged parts.
- Metallic rattling, which could point to issues with the strings or damper system.
If you notice persistent odd sounds while playing different passages, it may signal areas that need closer examination.
Step 5: Check Core Components
Once you’ve evaluated the sound quality, it’s time to inspect the piano’s key acoustic parts. These components play a major role in the instrument’s performance and overall worth.
Examine the Soundboard
The soundboard is central to a piano’s acoustic system. Here’s how to inspect it properly:
- Shine a light across the entire surface to spot any imperfections.
- Look for cracks, which often appear as dark lines following the wood grain.
- Check for signs of water damage or discoloration, especially near the edges.
- Tap different areas to detect any "dead" spots where sound is muted.
- Assess the crown, the slight upward curve of the soundboard. A flattened board could be a sign of age or wear.
At Cooper Piano, technicians use specialized tools to thoroughly assess soundboard integrity. Even small cracks can alter tone projection significantly. After the soundboard, move on to the bridges, which are responsible for transferring string vibrations.
Inspect the Bridges
The bridges are essential for transmitting string vibrations to the soundboard, so their condition directly impacts sound quality. Here’s what to check:
- Visual Inspection: Look for any gaps or separation between the bridge and the soundboard.
- Physical Check: Gently press both sides of the bridge to ensure it’s stable.
- String Alignment: Confirm that strings are evenly spaced and properly aligned.
A properly maintained bridge should meet these criteria:
- No visible gaps between the bridge and the soundboard.
- Bridge pins that are clean, intact, and secure.
- Strings that are evenly spaced, with no pins pulling away.
- No signs of splitting or cracking along the bridge caps.
If you find multiple issues with these components, it might be time to call in a professional piano technician. Their expertise will help you determine whether repairs are practical and how they might affect the instrument’s long-term performance and value.

Look carefully at the strings for signs of rust, wear, or breaks. Strings in good condition should be free from corrosion and intact.
Assess Tuning Pin Stability
Check that each tuning pin is firmly in place and holds tension properly. If you come across several loose pins or extensive damage to the strings, it’s wise to consult a professional before making a purchase.
Step 7: Test All Pedals
Once you’ve inspected the strings and tuning pins, it’s time to evaluate the pedals to wrap up your functional check.
Pedals play a crucial role in a piano’s performance. Each one should move smoothly, respond properly, and produce the correct sound.
Test Pedal Movement
Press each pedal and observe how it moves. It should operate smoothly without any sticking or looseness. If a pedal feels stuck, wobbly, or doesn’t return to its original position, there may be a mechanical problem that needs attention.
Listen for Pedal Noises
Pay attention to any unusual sounds, like clicking or squeaking, while using the pedals. A properly maintained pedal should work quietly. If you notice these noises, it could mean the pedal mechanisms are worn out or misaligned.
Step 8: Test Tuning
Once you’ve checked the keys, sound, and mechanical components, it’s time to evaluate the piano’s tuning. This step ensures the piano maintains a steady pitch across all octaves.
Check Pitch Accuracy
To assess pitch accuracy, focus on the following:
- Strike keys in various sections of the keyboard to identify any unstable or uneven tones.
- Play intervals like thirds, fifths, and octaves to evaluate how well the harmonic relationships hold up.
- Test major and minor chords in different positions to ensure the tuning is consistent throughout.
Review Tuning History
A piano’s tuning history can reveal a lot about its upkeep and potential issues. If the piano hasn’t been tuned regularly, there could be underlying problems that might require extra attention or repairs.
