How to write in score?

[maczip]

Hi, please I do need your help. I am trying first steps into Jazz improvisation. Here is a short recording of a motif, which I wonder how to write it down as a score.

The song is 4/4. LH plays on 1, 2, 3, 4. RH plays somewhat like triples, but they are no real triples. I donīt understand.

Thank you

This is kind of a swing rhythm.  In a swing pattern you always have a longer note followed by a shorter note.  So it is kind of like dotted eighth note followed by a sixteenth note, but not that extreme.  Actually it is closer to a triplet pattern with quarter followed by eighth note, right?  But it is not some exact mathematical relationship but rather something that is played by feel. 

There are a few different ways to notate this kind of thing, but simplest is just to mark them all as eighth notes and indicate that the eighth notes are to be swung.  So the motif you show here would have two eighth notes on count three and then two on count four, and the last one is tied to a long note starting the next measure (which creates some syncopation).  Then it is up to the performer to just hold that first eighth note of each pair a little longer than its value to create that swing.
