On a subject:
EC music is just music, it's not any different from flute or violin, or piano music.
...snip ...
For easy beginner's stuff you can use any student book for violin and flute, some easy arrangements for accordion's right side. I haven't tried it yet, but may be Guitar music will suit EC better. I'm testing this premice and learn very simple Hungarian Gypsi guitar arrangement "Mar dyandya" (Dance, Girl)
Micha,
You're right in that you can render a simple melody on the EC just as well as on any other instrument. But when it comes to elaborate arrangements like your "Dance, Girl" on the guitar, the music does become different. It's not just a matter of having all the notes in the range of your instrument. There are essentially two types of note production:
With woodwind, bowed strings, and free reeds, we get a continuous sound that we can hold (more or less) as long as we like, and we can crescendo and decrescendo each note while it is sounding.
The plucked and hammered strings are different: once the note is sounded, it is out of our control. We can damp it out, but we can't influence its volume. How long the note can sound (the sustain) is a feature of the physical instrument. Pianos have a long sustain (and an elaborate damping system to deal with it), guitars have moderate sustain, and banjos have little sustain.
The wind and bowed instruments have no sustain. When you stop bowing or blowing, the note dies instantly.
These characteristics become very important when you're arranging for a specific instrument. Even classical guitar and classic banjo arrangements are different - banjo arrangements are more "notey" to cover up for the lack of sustain. A banjo arrangement transferred to the guitar would sound "mushy", because the sustain would tend to run the notes together. A guitar arrangement transferred to banjo, on the other hand, would sound very "plunky" and disconnected.
In that Russian piece on Youtube, the guitarist makes a lot of use of the sustain of the open bass strings while doing intricate fingering on the treble strings. This just cannot be transferred to free reeds. Either you'd have to just play the bass notes for one beat - leaving the high notes unsupported - or hold down the bass button for the written duration, which is not the same as a gradually decaying, plucked note. In either case, the effect is totally different, and in most cases will not be as good.
I could imagine adopting the melody and chord structure of a guitar piece for EC, but not the score of an arrangement. (We "by-ear" players are at an advantage here - we hear the melody and the chord changes, and we implement them in a way that the respective instrument offers. Improvisation is always a dialog between player and instrument - and I believe that good instrumental arrangement should be similar.)
I would expect violin and oboe pieces to come across well on EC (which has the range of the violin, hasn't it?). The absence of sustain, the ability to hold notes, and the flexible dynamics are the same. But the disadvantage is that all oboe music and all simple violin music is single-note melodic, and requires an accompaniment. To do justice to the EC, the violin arrangement would have to feature heavy double-stopping.
Transcription is not a simple matter, and not all pieces are transcribable.
My Russian bayan-playing acquaintance plays a lot of transcribed keyboard works. But most of them are organ pieces (which are ideal for the bayan) and baroque harpsichord works. The harpsichord has little sustain, so in the music written for it the notes come out sequentially. Romantic piano works do not go well on the bayan (says my friend), because he has no sustain pedal. He can simulate an organ pedal note, but not the effect of slow decay that a piano sustain pedal gives you.
Accordion right hand scores sound like a good source for EC arrangements.
Cheers,
John
