To provide an illumination device capable of fully meeting the demand of viewers who want to enjoy viewing a painting or the like with sound providing a great sense of ambience, and a frame provided with the illumination device. The illumination device includes a signal reception unit (50) capable of receiving an audio signal from outside, a musical piece extraction unit (60) capable of extracting continuous consonant sounds in the audio signal as a musical piece, a performance state detection unit (70) capable of detecting start/end of performance of the musical piece according to a result of extraction by the musical piece extraction unit (60), a first illumination lamp capable of radiating ultraviolet rays, a second illumination lamp capable of radiating white light, and an illumination control unit (23) capable of controlling on/off of the first illumination lamp, and of controlling on/off and illuminance of the second illumination lamp, where the first and the second illumination lamps are turned on in response to detection of the start of performance, and the first and the second illumination lamps are turned off in response to detection of the end of performance.

When a processor receives inputs of plural notes (Nt1, Nt2, Nt3, Nt4), for instance from a keyboard, to be assigned for tone generation, according to a predetermined note determining musical rule called "assignment type" (harmony), the processor autonomously selects (S3), out of the received notes, one or more notes to be sounded in each of plural parts (Parts 1, 2, 3, 4).

The processor controls (S4) a display unit (13) to display, for each of the plural parts, the selected plural notes to be assigned for tone generation. Non-selected notes in respective parts are displayed in one style, and the selected one or more notes in the respective parts are displayed in another style (S44).

An electronic device and a method for high speed visualization of an audio stream are provided. The method of operating the electronic device includes extracting only header information from at least one frame included in a specific audio file, extracting a global gain value, which is an average volume of respective frames, by using the extracted frame header information, filtering the extracted global gain value, and displaying the filtered value.

Tone generating style notification control apparatus is provided for an electronic or natural musical instrument having a mouthpiece section operable with a human player's mouth. Detection is made of a physical amount caused by operation performed on the mouthpiece section with the mouth, and a tone pitch corresponding to the detected physical amount is identified by referencing a storage section storing information defining relationship between various values or ranges of the physical amount and tone pitches. Expected tone generating style is notified to the player on the basis of the identified tone pitch. As another example, a storage section contains a tone pitch table defining relationship between various ranges of the physical amount and tone pitches, and a gain table defining, as gain information, values corresponding to deviations of the physical amount from a predetermined reference point for each tone pitch and within the range of the physical amount corresponding to the tone pitch. For the detected physical amount, a tone pitch is identified by referencing the tone pitch table and gain information is identified by referencing the gain table, so that the identified tone pitch and gain information is notified.
