An assistive music playing apparatus plays a music piece with musically acceptable notes even when the player inputs musically unacceptable notes. The apparatus provides a chord progression pattern, and comprises a note conversion device. A chord progression pattern defines a series of chords, which are presented one after another in time for a music progression. As the player plays music, inputting potentially unacceptable notes, the inputted notes will be converted to musically acceptable notes with reference to the currently presented chord in the chord progression. The note conversion rules are prepared different for a melody note range, a chord note range and a bass note range. Overlap of converted notes are avoided. Depending on the conditions of the player's note input, i.e., whether the melody is ascending or descending, or the chord is played in a block chord or in an arpeggio, the conversion rules may be selected to generate notes which fit the designated chord, even including non-basic notes or tension notes.

In a network performance system involving a plurality of performance apparatuses, each performance apparatus stores phrase performance information of a plurality of performance parts, and each performance apparatus is allocated with one of the performance parts to conduct an ensemble performance composed of the plurality of the performance parts. A server apparatus is connected to each of the performance apparatuses via a network. Each of the performance apparatuses is manually operable to input operational information relating to the performance part allocated thereto, and transmits the inputted operational information to the server apparatus via the network. The server apparatus delivers the operational information transmitted by each of the performance apparatuses to other of the performance apparatuses via the network. Each of the performance apparatuses receives the operational information relating to other performance parts allocated to other of the performance apparatuses from the server apparatus via the network, and reproduces the phrase performance information of the performance part allocated thereto in response to the inputted operational information and concurrently reproduces the phrase information of other performance parts allocated to other of the performance apparatuses in response to the received operational information to thereby conduct the ensemble performance composed of the plurality of the performance parts.

Network system for ensemble performance by remote terminals

A music apparatus is communicable with a supervisory computer through a network for remotely training a user in matching with a skill level. In the music apparatus, an instrument is manually operable by the user for generating a performance. A monitor displays a lesson score in matching with the skill level so that the user is prompted to render the displayed lesson score by operating the instrument for generating a sample performance. A processor compares event data representative of the sample performance with note data representative of the lesson score to locally execute a quantitative evaluation of the sample performance. A transmitter transmits the event data representative of the sample performance to the supervisory computer through the network so that the supervisory computer can work to remotely provide a qualitative evaluation of the sample performance according to the event data to thereby arrange instruction data. The qualitative evaluation is different from the quantitative evaluation and is locally unavailable. A receiver receives the instruction data from the supervisory computer through the network to pass the instruction data to the processor. The processor operates based on either of the local quantitative evaluation and the remote qualitative evaluation represented by the received instruction data for modifying the lesson score effective to improve the skill level of the user.
