Here are some suggestions for easy beginning:
Basic musical hints:
- beat: 4/4 (also 2/2 or 3/4 are possible)
- tempo: around 120 b.p.m. (funeral marches sometimes only 60 b.p.m.)
- accentuation on beat 1, 2, 3 and 4, whilst beat 1 is a little bit more accentuated than the other beats
- mode: mostly major, if it is not a funeral march
- key: use b-keys for easier playing with brass instruments in f, bb or eb
Instrumentation:
- use (snare) drums, timbals, trumpets and swiss pipes for a 16. century sound (when the sovereign entered the town or went to wage war)
- add more brass for modern marching band instrumentation, such as horns, trombones and tuba
- try woodwind instruments (transverse flutes, saxophones, oboes, bassoons) and may be a glockenspiel (e.g. bell lyra)

Composition:
- try to define melodies that can be remembered and piped/sung easily
- create a melody with no shorter notes than 1/8 (as a basic rule only)
- use syncopes for modern style pieces only
- harmonisation depends on style also, so use triads or 4-note-chords for classical diatonic harmonies (e.g. expanded by secondary dominants) and more upper structures for jazz styles
- try sections of 8, 16 or 32 measures and reprises of 8 to 16 measures
- add a melodious trio (often in the key of the subdominant)
- eventually include drum solos
The rest of the composition work as I prefer doing it is to start with melodic, harmonic and accentuation impressions and then begin to structurize. Sometimes I have a voice recorder with me and just sing or say what comes into my mind while strolling, notation is the evening work then.
Good luck!
