Piano Technology & Digital Applications 4

Question 1

Which piano learning app feature uses the camera to track a student's hand position and flag tension in real time?

Accepted Answer

AI posture and hand analysis via computer vision

Answer

Some modern apps use machine learning and the device camera to analyze hand shape, wrist angle, and tension during practice.

Question 2

In a virtual piano sample library, what is 'round-robin sampling'?

Accepted Answer

Using multiple recorded samples per note that rotate on repeated strikes to avoid a machine-gun effect

Answer

Round-robin sampling alternates between several recordings of the same note so repeated notes sound natural rather than identical.

Question 3

What is the main advantage of using a weighted-key MIDI controller over a non-weighted keyboard for piano practice?

Accepted Answer

They simulate the hammer action of an acoustic piano, developing proper finger strength and touch sensitivity

Answer

Weighted keys replicate the resistance of acoustic piano hammers, training fingers appropriately and enabling expressive velocity control.

Question 4

Which technology enables a Bluetooth MIDI device to connect to a tablet without a USB cable?

Accepted Answer

BLE-MIDI (Bluetooth Low Energy MIDI)

Answer

BLE-MIDI (also called MIDI over Bluetooth LE) is the standard protocol allowing wireless MIDI communication between devices.

Question 5

When a piano app displays a 'metronome with subdivisions,' what additional information does it provide over a basic metronome?

Accepted Answer

It clicks on every beat AND smaller rhythmic divisions (e.g., eighth or sixteenth notes) within each beat

Answer

Subdivision clicks help pianists internalize smaller note values within a beat, improving rhythmic precision for faster passages.
