Abstract
The invention discloses an accordatura device and its achieving method. The accordatura device comprises a single machine unit, a press key input unit, a display output unit and an audio output circuit, which is characterized in that the press key input unit arranges a group of piano keyboard type press key and a function press key switch which is corresponding to the real musical instrument keyboard. The method comprises the following steps: a. it uses the corresponding press key to input the order; b. the single machine unit finds out the stored standard sound code by the inputted order; c.it generates an audio signal output of the standard sound by the code and displays the name, group order, the arranged A4 value and the indicating sound on the staff sent by the outputting unit at the same time.
Description
technical field [0001] The invention belongs to the category of electronic musical instrument parts, and more specifically relates to a tuner and its realization method. Background technique [0002] Pitch training is an important part of learning music. It mainly cultivates the ability of judging the pitch of the music learners. Most beginners do not have the ability to judge the pitch accurately. They need to do a lot of repeated ear training. Practice the position of finger touching the string and the strength of pressing the string to accurately control the pitch. [0003] The traditional method is to let the music learners perform solfeggio and ear training to achieve accurate control of pitch, but this requires special training courses and takes a lot of time. Especially for non-coded string instruments such as huqin and violin, unlike piano, dulcimer, pipa, guitar, etc., which have clear pitch playing positions and code positions, the intonation must be controlled th...
