Exemplary systems and wearable haptic device systems are disclosed for training a user to improve perception or discrimination. An exemplary system can be used to train a user to play a musical instrument, such as a piano, in passive training sessions via a wearable haptic device. The exemplary wearable haptic device can be integrated with sensors and in operative communication with a passive haptic learning system (e.g., cloud-based infrastructure) that is configured to generate, update, and/or modify tactile training data for generating tactile outputs at the wearable haptic device.

An apparatus for playing chords, scales and/or intervals on a musical instrument for visually-impaired people is provided. The apparatus can have a substantially rectangular card with multiple indicators attached to the card that a visually-impaired person can play all chords, intervals and scales on a piano with a dedicated card having the chord or scale configuration by aligning the indicators to any piano key and finding the other keys of the same chord or scale on the piano by aligning the other indicators.

A simulated musical string instrument formed of plural shaped sheets of rigid material, such as cardboard. There is a top sheet forming a top surface of the simulated string instrument body, and a bottom sheet forming a bottom surface, and multiple sheets between. A simulated fingerboard is attached to the top surface. The top sheet and fingerboard gets stickers that show parts of the simulated string instrument body including openings and notes. There is also a simulated bow guide and a simulated bow.

The present invention relates to a music chords conversion device. The device is used for providing instant representation showing conversion or correlation of major chords to minor chords and vice versa. The device can come in two variants (1) a physical device (2) a digital device. The physical device has a chords conversion component and a minor chords component wherein the minor chords component is configured to slide into the chords conversion component through a cut-out opening. The minor chords can be correlated to the major chords and displayed in a viewing region of the chords conversion component. The digital device includes a memory for storing the chords conversion and also includes a digital display for displaying the converted minor and major chords.
