I have some suggestions if I may, understanding that an awful lot of work must go into these productions but suspecting you would welcome feedback.
It may be interesting to have the bits of analysis at the beginning with short musical extracts before then playing the whole work which is only accompanied by the score or pictures and other information about the composer, performers etc.
I would like some transitions between each screen image, say a 2 second fade out and in when appropriate. At the moment the sudden changes are a little distracting, something to be avoided especially when listening to Delius.
More pictures of the composer or anything to do with him and the performers if available, related works of art etc. Perhaps even some moving images of sympathetic landscapes or places. A description of every screen image would be helpful for those of us not so familiar with the references.
Even with static images some panning in and/or out would add interest. For instance the picture of Delius (I assume it was he) could have slowly panned into just his face before moving on to the next image.
A "Third Programme" play out as with the play in and some credit for the producer.
Many thanks Mr. Porcus; I'm glad you enjoyed it. Your comments and suggestions are most useful, and I will have them all in mind when weighing up what to put in and where to place the various bits and pieces. I'll have to find out the technique of fading in and out. Two further techniques in prospect are fonts with kerning and ligatures, and the incorporation of extracts from films. I hope that there will eventually be hundreds of these broadcasts; plenty of scope for improvement and the learning of new methods.
