It's great to know that most of us who like making music are passionate about composing, writing and recording our own material.  Can the track you're working on be helped by adding some flute or saxophone lines?

In the current climate going out to visit an instrumental tutor or having one come to you might not be possible.

Whatever the genre of music you like to creatively improvise over - you need to know the basics.  Learning to hear and speak the language of jazz  will help to get you moving in the right direction.
