Musicians must spend a substantial amount of time learning the positions of chords/notes on new instruments they are interested in learning. Facilitated instrument learning will allow someone to sing, hum, or play another instrument and the currently played notes will be mapped onto the new instrument in real time. This allows a beginner, with little musical background, to sing a melody they wish to play and learn it on a new instrument and also allows a professional, with an extensive background on musical theory and other instruments, to compose music on new instruments.

The acoustic input is recorded through an analog MEMS microphone and the signal will go through an ADC. This will connect to a DSP chip which handles the frequency analysis. This will connect to a microprocessor which controls the LEDs on the piano keys.

The DSP chip analyzes the notes currently being struck by filtering and removing the harmonics from the spectrum. The frequencies of the notes will correspond to positions on an instrument which can be indicated by LEDs.

A 9V battery connected to voltage regulator will supply the necessary supply voltages to the components.

Other products which help people learn instruments are:
This $2000 product is limited because notes must be pre-selected on the piano for students to learn from later. With the proposed project, users produce the melodies with their voice or an instrument and the notes on the destination instrument will be shown in real time.
This piano learning subscription service is limited to select songs the company has pre-transcribed for its users, so customers are unable to write songs with melodies they have come up with.

Drum Tutor Lite

Featured Project

Team: Yuanheng Yan, Zhen Qin, Xun Yu

Vision: Rhythm games such as guitar hero are much easier than playing the actual drums. We want to make a drum tutor that makes playing drums as easy as guitar hero. The player is not required to read a sheet music.

Description: We will build a drum add-on that will tutor people how to play the drums. We will make a panel for visual queue of the drum and beats in a form similar to guitar hero game. The panel can be a N*10 (N varying with the drum kit) led bar array. Each horizontal bar will be a beat and each horizontal line above the bottom line will represent the upcoming beats.

There will be sensors on each drum that will fire when the drum heads is hit. The drums will be affixed with ring of light that provides the timing and accuracy of the player according to the sensors.

Of course with a flip of a switch, the drum could be a simple light up drum: when the player hits the drum, that particular drum will light up giving cool effects.

The system will be on a microprocessor. Or for more versatile uses, it could be connected to the computer. And a app will be written for the tutor.
