How Treble. Alto and Bass clefs relate:

hmmm.... not sure if that graphic would be too helpful to someone learning how to arrange. Worth noting that Bass and treble clef come in multiple "flavors" and that there is a huge diff. in how to write depending on what key the instrument is in. Eb. Bb and C (the most common treble clef instruments and keys I can think of are VASTLY different). OP suggest you pick up a book on this it is a complex topic if you are new to it. On the bright side - Alto clef is always in the same place - for any clef that looks like that; the center marks where middle C is for whatever voice is going to play it. Bass Clef, of "F Clef" uses the colon to tag where F 8vb from middle C is (unless the clef itself has an 8 or a 12 or 15 above or below it) - treble clef is .... no matter who you are, what you write or how you play a clusterf---.
