can someone teach me how to play in treble clef? or give me some advice?

I've had orchestral cello parts in which someone had penciled in the note names in the treble clef sections. I had to laugh; it's the tenor clef part I struggled with. For years I was in the habit of reading the tenor clef by imagining the notes in question to be treble clef notes and then taking them a diatonic ninth down. Conversely, I was in the habit of reading the alto clef (in orchestral scores--viola parts) by imagining the notes in question to be treble clef notes and then taking them a diatonic seventh down.

These are bad habits, and I advise you not to fall into something analogous in respect to the treble clef. Do two things: Practice regularly with the the note reader on this forum, and get some very easy music written for an instrument that normally uses the treble clef such as the violin, guitar, or flute, etc. and read through a little of it each day. Alternatively, you might just take up a treble clef instrument.
