Understanding Sustain Pedal Polarity Switch in Keyboard Music: Tips from UrbanPro.com's Keyboard Music Tutors

As experienced keyboard music tutors on UrbanPro.com, we're here to explain what a sustain pedal polarity switch is and when it's used. The sustain pedal is a valuable accessory for keyboardists, and understanding this feature can help you make the most of your music. Here's a detailed explanation:

1. Sustain Pedal Basics:

• The sustain pedal, often referred to as a damper pedal, is an essential accessory for keyboardists. It allows you to sustain the sound of the notes you play, adding depth and richness to your music.

2. Sustain Polarity:

• Polarity, in this context, refers to the direction in which the pedal's switch operates. Keyboards come with two types of sustain pedal polarity:

  • Normally Open (NO): In this setting, the switch is open (off) when the pedal is not pressed and closes (on) when you press the pedal.
  • Normally Closed (NC): Here, the switch is closed (on) when the pedal is not pressed and opens (off) when you press the pedal.

3. Choosing the Right Polarity:

• The choice of polarity depends on the type of sustain pedal you have. It's essential to select the correct polarity to ensure the pedal functions as intended.

• Check the specifications of your keyboard and the pedal to determine which polarity setting is compatible.

4. Why Polarity Matters:

• Using the wrong polarity setting can result in an opposite pedal behavior. For example, with a mismatched setting, pressing the pedal may cut off the sustain rather than activating it.

5. How to Set Polarity:

• Most keyboards come with a polarity switch or setting. To adjust the polarity, follow these steps:

  • Locate the polarity switch or setting on your keyboard or in the pedal's user manual.

  • If it's a physical switch, change it to the correct setting (NO or NC) based on your pedal's specifications.

  • If it's a software setting, access the keyboard's menu or settings and make the necessary adjustment.

6. Testing Polarity:

• It's a good practice to test the polarity after making the adjustment. Simply press the sustain pedal and observe if it behaves as expected. If not, recheck and ensure it matches the pedal's polarity.
