Because talent show was the trend especially on vocals, many people interested in learning singing. But there are problems in practice singing, the problem is difficult to adjust the pitch of sound when singing. Now, to train pitch of sound needed vocal teachers, but they will have limited in terms of time and financial, because vocal course with teacher is expensive and difficult to make exercise schedule. Traipitch is a device for guidance in pitch adjustment of the human voice. Traipitch will guidance the user by visual representation of the note sung by the user. Traipitch will receive a user input through microphone, then a device will display the difference frequency between tones reference and tone of user voice in smartphone. Traipitch is divided into multiple subsystems, namely the signal conditioning circuit, the analog-digital converter, the pitch detection algorithm, the Android application, and the power supply. Power supply must be able to supply all the power on this device, in order for the system run properly. Traipitch app is an Android-based app. This app uses bluetooth as a communication system, to received and send data from device to app. There are several exercise menu in Traipitch app, that can be selected according to the number of users. In one user menu, exercise menu are BASIC 1, BASIC 2, HOLD THE PITCH, ADVANCED, and SELECT TONE. In two users menu, exercise menu are TONE TRAINING, and LET’S SING. <p align="justify">
