A pitch raise is a specialized piano tuning procedure that becomes necessary when a piano has fallen significantly below its standard pitch. Understanding when and why your piano might need a pitch raise can help you maintain its optimal performance.

What is a Pitch Raise?

A pitch raise is a process where a piano technician raises the overall pitch of the piano to bring it back to standard concert pitch (A440). This is different from a regular tuning, as it involves significant adjustments to all strings simultaneously.

When is a Pitch Raise Needed?

• After long periods without tuning
• Following significant climate changes
• After moving the piano to a new location
• When the piano is more than 20 cents flat
• Before a performance or recording session

The Pitch Raise Process

The process typically involves two steps: first, a rough pitch raise to get the piano close to the correct pitch, followed by a fine tuning to achieve precise pitch and stability. This two-step process is necessary because the tension changes in one part of the piano affect the tension in other parts.

What to Expect

• The process takes longer than a regular tuning
• Multiple passes may be needed
• The piano may need a follow-up tuning
• Some temporary instability is normal
• The final result should be stable and in tune

Preventing the Need for Pitch Raises

Regular maintenance is the best way to prevent your piano from needing a pitch raise. This includes consistent tuning schedules, proper humidity control, and avoiding extreme temperature changes. If you notice your piano sounding significantly flat, schedule a service call as soon as possible.

Professional Considerations

Pitch raises should always be performed by a qualified piano technician. The process requires specialized knowledge and experience to ensure the piano's structural integrity is maintained. Attempting a pitch raise without proper training can lead to broken strings or other damage.
