A digital piano having fixed solfège syllable keys, enabling non-stepped key changes and keypress-based sound variation, and facilitating sight singing. The piano enables continuous key variation, employs non-stepped key changes, and enables, during play, fine modulation of the pitch by means of key pressing, thus adjusting the temperament and timber accordingly. The piano has a keyboard with fixed solfège syllables; namely, each set of keys of the keyboard directly corresponds to an octave of the numbered musical notation, and each key continues to correspond to the same solfège syllable after the key is changed. A color vector image-based display based on the numbered musical notation is provided to enable a musical score to be displayed in colored images, pitches are expressed with expanded solfège syllables, colors are used to express spatial positions of the keys, notation squares having a fixed width are used to express note values, and font boldness of notation symbols is used to indicate note playing strength. The present invention provides multi-dimensional playing information, is suitable for computer-based digital score recording, has multiple display modes, and helps beginners to quickly learn to play piano by using the color vector image-based display of the numbered musical notation in combination with sight singing.
