Exploring Aftertouch in Keyboard Playing: A Guide by Keyboard Music Tutors on UrbanPro.com

As registered keyboard music tutors on UrbanPro.com, we are here to elucidate the concept of aftertouch in keyboard playing. Aftertouch is a nuanced technique that adds expressiveness and depth to your keyboard performances.

1. Introduction to Aftertouch:

• Aftertouch, also known as "pressure sensitivity" or "channel pressure," is a performance technique unique to many modern electronic keyboards and synthesizers.
• It allows you to modulate various parameters of the sound while holding down a key after the initial keypress.

2. How Aftertouch Works:

• Aftertouch is activated by applying additional pressure to a key while it's held down. The keyboard senses this pressure and translates it into a control signal.

3. Types of Aftertouch:

There are two main types of aftertouch:

a. Channel Aftertouch: - In channel aftertouch, the applied pressure affects all notes played simultaneously, often influencing parameters like vibrato, volume, or filter cutoff across the entire sound. - Channel aftertouch is usually generated from the overall pressure applied to the keys.

b. Polyphonic Aftertouch: - Polyphonic aftertouch is more advanced and allows individual control over each held key, even when multiple keys are pressed. - It provides a higher level of expressiveness, as you can independently modulate parameters for each note.

4. Applications of Aftertouch:

• Aftertouch can be employed in various ways to enhance your keyboard playing:

  a. Vibrato Control: - Apply aftertouch to add vibrato to sustained notes, creating a dynamic and expressive sound.

  b. Volume Swells: - Use aftertouch to control the volume of a note or chord after it's played. This is particularly useful for creating swells and fades.

  c. Filter Modulation: - Aftertouch can be mapped to adjust filter cutoff frequency, allowing you to sculpt the tone of your sound in real-time.

5. Incorporating Aftertouch into Your Playing:

To make the most of aftertouch in your keyboard playing:

a. Familiarize Yourself: Get to know the aftertouch capabilities of your specific keyboard. Refer to the manufacturer's manual for guidance.

b. Practice Control: Develop finger control to apply consistent and intentional pressure without altering pitch or velocity.

c. Experiment: Experiment with channel and polyphonic aftertouch to understand their unique applications.

d. Mapping: Some keyboards allow you to map aftertouch to specific parameters. Explore these options to customize your sound.
