Abstract
In an electronic tuning apparatus used in electronic stringed instruments such as an electronic guitar, an electronic violin, and so on, at least one string is extended along the fingerboard. Prior to picking performance, a present state of the extended string is examined through picking said string. Preferably, a reference pitch data extracted through the string-picking manipulation is stored. During a live picking performance, a performance-pitch data extracted is converted into a data for defining a properly-tuned sound-frequency in accordance with said extended string state. A musical-tone having a corresponding sound frequency is generated based on data for defining said sound frequency.
