Those who do speak a language other than their native tongue know above statement to be true.
For the moment you start speaking another language you immediately are drawn into the culture of the country and people who speak that language. It is quite remarkable and one of the main reasons I enjoy returning to Europe where I can speak Dutch, German or even a bit of French or Spanish. For each language a different perspective of my personality comes to the fore.

Another thought, very much in line with Charlemagne's profound statement, struck me the other day when I was listening again to one of my Jazz compositions, Coming Home I had recorded in 2008.

Most of the 80 or more songs I have composed over the years illustrate specific educational aspects of music in my lessons, but a dozen or so I wrote prompted by a special mood or emotion.

Coming Home is one of those. It expresses the feeling of joy and happiness when returning home to the one you love.
Modern day digital sampling of the sounds of various instruments is absolutely amazing.
They are so realistic that, unless you actually see the keyboard player playing a synthesizer, you would swear the performer was playing a guitar, a saxophone or a flugel horn.

The sound also has a profound effect on the mind and creative direction of the performer.
Although you are playing a keyboard, feeling the keys with your fingers, the sound produced instantly draws you into the nature (read "culture") of the instrument it belongs to.

My recording of Coming Home shows this aspect well.
The recording covers 4 choruses of the song. The first chorus is the melody played with a acoustic guitar sound. The following three choruses are improvisations played with the sounds of a vocal group, then a tenor sax and finally the acoustic guitar (which repeats part of the melody over the final 8 bars).
The different moods reflected by the three instruments are shown in the following table.
