Railroad tracks

Thanks to one of the lovely members of yahoo's harplist, I now know the the double slash (\\) marking in Berceuse is a caesura.
Caesura - (/siːˈʒjʊərə/ or /sɪˈʒʊrə/; alternative spellings are cæsura and cesura) is a complete pause in a line of poetry or in a musical composition. In musical notation, caesura denotes a brief, silent pause, during which metrical time is not counted. --from Wikipedia.

Next is to figure out if I want it to be a L.V. pause or a muffled pause.

A couple definitions I missed

Senza misura - an Italian musical term for "without meter", meaning to play without a beat, using time to measure how long it will take to play the bar. (wikipedia)
Ten. (Tenuto) - Italian, past participle of tenere, "to hold". The precise meaning of tenuto is contextual: it can mean either hold the note in question its full length (or longer, with slight rubato), or play the note slightly louder. In other words, the tenuto mark may alter either the dynamics or the duration of a note. Either way, the marking indicates that a note should receive emphasis. (Tom Gerou and Linda Lusk, Essential Dictionary of Music Notation (1996))

Some definitions

As I'm working on dynamics, I'm playing much louder and consequently gotten the skin on the pads of my fingers to that really squeaky point that comes just as blisters are forming.  Here's proof. Ow.

I forgot yesterday when I analyzed my pieces that I didn't know what the composer was asking for. So here is a vocabulary list:
Maestoso - ma·es·to·so  (mäs-ts, -z) adv. & adj. Music In a majestic and stately manner. Used chiefly as a direction. [Italian, from maestà, majesty, greatness]
Poco accel. (poco accelerando) - go faster little by little
Sempre - sem·pre  (smpr)adv. Music In the same manner throughout. Used chiefly as a direction.[Italian, always, from Latin semper]
Conto - a monetary unit in Portugese? Ah. Lento. Italian for WRITE LEGIBLY.
Cantando - Singing style. ?
Più moto - more motion.
Più agitato - more agitated, with implied quickness.
Velocissiomo - very fast, very quick, very speedy.
There are also some commas and double slashes (\\) at the ends of some measures. Commas denote a breath mark for singers. Double slash = ?
