More Bandpass Filter Videos

The videos below show you how we can use bandpass filters to identify out-of-tune unisons and clean them up.

Learn How YOU Can Get Superior Tuning Results!

By now, I hope you are convinced of the power of bandpass filters.

At the International Piano Technicians School, we are able to train students to

Score 100%

on many sections of the RPT exam, and have them evaluated as

Concert Level Tuners!

by independent concert piano technicians!

We can do this using bandpass filters and the following powerful techniques that are only taught at the International Piano Technicians School  

• Tuning two strings at once (Double String Unison, DSU)
  
• Non-Speaking Length (NSL) Tension Analysis for superior stability
• Unison concepts like "the Word", etc.
• Beat Speed Windows
• Stretch Interval Set (SIS)

International Piano Technicians School is the only school in the world, online or in-person, that is able to train students to get concert level results. Stephen Struwve was evaluated as a concert level tuner after only

21 Weeks, and Only 42 hours!

of online lessons.

We can do this because we are the

The Only School in the World!

doing research and developing techniques like DSU and NSL Tension Analysis, and Beat Speed Windows, and the SIS. No other school in the world teaches these techniques. That's why

Our Students Excel and Perform Better Than Other Students!
