On a piano performance

One of the reasons why I am attracted by piano performance is that there exist a moment when the left hand part’s notes and right hand part’s notes are weaving and entangled. In my theory, the relation between lower and upper part can be stated by a parameter, which can be expressed as ‘mutual distance’ or ‘independency’. It’s different from the completeness of chordal resonance. Sadly, I don't have an ability to describe what kind of unit this parameter is expressed by, but it’s certain that the state of two melodies’ mutual distance sometimes send a signal to our ears dramatically.

Though each part is played independently, the ‘mutual distance’ between them can be varied from ‘distant’ to ‘entangled’. A chorus of a piece, I think, had better be played in an entangled state. However, in many cases and at least for me, two parts seem to be played mutually distant, from a beginning to an end.

Luckily, we can enjoy an entangled state a little in this performance found on Youtube, on which two parts are weaving as shown in figure above.

A present for Si’s 100th birthday

Making chronological table sometimes help us find a different viewpoint of things already known. This time, I picked up Si and challenged to make its chronological table. I don’t know whether 100^th anniversary was celebrated or not in 1928 for Berzelius’ Si isolation. Perhaps not celebrated so much. I guess that the importance of Si was not recognized in those days except for certain people.

However, if we look back based on the figure above, it is clear that the discovery of Schrodinger equation, the foundation of quantum mechanics and band theory that followed, which opened the door to the semiconductor age, was a great present for Si’s 100^th birthday. Without quantum mechanics, Si would have continued to be the Si under 100 years old, which seemed to have no possibility of changing the whole lifestyle of us.

On NW-A845 (3) Operability

To be honest, I feel that the operability of old type Ipod is better than that of NW-A845. Pinpointing my thumb on the right position of the concentric circle on NW-A845 usually doesn't go smoothly. In particular, when operating in one hand, recognizing which part of the concentric circle my thumb is touching isn't so easy without seeing it, while Ipod’s slightly convexed circular dial is easy to identify intuitively only from tangible information.

In addition, the silver concentric circular dial allocation is too low-positioned to operate with thumb in a situation of gripping whole body. Little finger operation would be required if we anticipated Ipod-like operation.

As for Ipod, an idea of the combination of that slightly convexed, relatively big, nearly center positioned and circular dial opened the door to today’s Ipad fever.

However, in today’s situation, I think Sony doesn’t have to introduce the same method as old type Ipod into NW-A845. The next step required for NW-A845 is, in my opinion, ‘a slot-machine-like' menu operation on touch panel working in present screen size. Above figure shows an image of the screen.

As a matter of fact, in handycam series, Sony has been presenting drum-like configuration menu as shown in figure below.
