This paper puts forward a safe mechanism of data transmission to tackle the security problem of information which is transmitted in Internet. We propose a new technique on matrix scrambling which is based on random function, shifting and reversing techniques of circular queue. We give statistical analysis, sequence random analysis, and sensitivity analysis to plaintext and key on the proposed s...

As people are living longer and enjoying better quality of life, there has been a corresponding increase in interest in recreational music making by adults. This study examined the demographics and motivations of students enrolled in the Community Piano Experience hosted by the University of Nebraska-Lincoln School of Music. Twenty-six participants completed Survey A before beginning the progra...

The pitches produced by toy pianos are sometimes perceived to be inaccurate by listeners, some of whom report perceiving the perfect fifth above the nominal note of the pressed key. To investigate these assertions, the overtone frequencies of a toy piano were measured in a frequency range of no more than the eighth harmonic and below 5 kHz, which are considered to be important to the pitch perc...

This study addresses the old question of whether the timbre of isolated piano tones can be audibly varied independently of their hammer velocities — only through the type of touch. A large amount of single piano tones were played with two prototypical types of touch: depressing the keys with the finger initially resting on the key surface (pressed), and hitting the keys from a certain distance ...

The carillon is one of the few instruments that elicit sophisticated haptic interaction from amateur and professional players alike. Like the piano keyboard, the velocity of a player’s impact on each carillon key, or baton, affects the quality of the resultant tone; unlike the piano, each carillon baton returns a different forcefeedback. Force-feedback varies widely from one baton to the next a...

De que modo podemos trazer abrangencia para a educacao ou formacao pianistica de professores, alunos e musicos-interpretes se sintam mais seguros tocando com autoridade performatica? Eis questao-problema questao-chave norteou o presente trabalho. Outrossim, fundamentamos nosso estudo no metodo analitico-descritivo base na Revisao Bibliografica. Neste artigo cientifico, comentaremos sobre as dif...

We developed an automatic piano performance system called Polyhymnia that is able to generate expressive polyphonic piano performances with music scores so that it can be used as a computer-based tool for an expressive performance. The system automatically renders expressive piano music by means of automatic musical symbol interpretation and statistical models of structure-expression relations ...

This study aimed to identify biographical predictors of children pianists’ motor skills in a relevant musical context. Motor skills at the piano were assessed in 30 piano-playing children by testing temporal evenness in standardized scale playing which is a basic element of piano technique. Questionnaires were used to collect detailed information regarding the practice habits and other biograph...
