Anyway...
Suffice to say that when arranging a piano piece for any type of quartet you are going to have to overcome some major hurdles, possibly constantly.
They are:
- deciding which notes of a chord to leave out
- deciding how to make "pianistic stuff" sound decent on single - note instruments
- deciding whether a change of key might better suit the range of your instruments
With the above rendition of Rockin' Chair, you'll be faced with all of these decisions.
Key choice - something that considers the lowest note of your bass instrument - in sax terms the Bari for a standard 4tet - and how you make use of the low Bb or A. In this case though, maybe more attention needs to be paid to the melody. In this Teddy Wilson style it's very light and melodic. High though, as far as soprano sax goes and not wanting to be ear - piercing.
Articulation is another factor. You can't merely transcribe from one instrument to another and expect similar techniques of playing to automatically sound good. Take the short, almost staccato articulation that was / is so great - sounding on piano; if the soprano sax played the same short notes it will probably sound more like a pastiche, and not jazzy. Same goes for some of that chordal movement. It could end up sounding more like Ragtime if not careful.
Which chordal notes to leave out can be either obvious at times, or really hard. Especially if the melody notes don't often take any of the stock notes from a chord. So, you might always be left with just 3 players doing the heavy lifting. You might get around it by having more movement - one or more players playing more than one note in the accompaniment. Great. But what if it's a well - known tune with the accompaniment as well - known as the melody? Like Eric Satie's Gymnopedies for example.
Anyway...
Agreed.
1. Tremelo is not a trill (they have different names to help us remember)
2. Tremelo is not a growl (my dogs tell me this incessantly)
