# 13 Archetypes: Listener

• ✭✭✭
• what is the format? how exactly is this supposed to be read like a-g if so how do I convert that to anything that makes sense? I am attempting to find how 13ar would work so the rest of it makes sense but no idea which way to go with it

OK, now I don't know what to count. On a normally tuned piano, there is no "C flat" key. That would just be "B"?

Similarly, no E#, which would be "F"?

• ✭✭✭

I have "ar", 13 is just a guess. I was using brute force 🤣 and this could be only a coincidence xD

• ✭✭

I think we don't need much musical note reading skill to solve this since this is not a valid score.

• but what exactly can we do with letters a-g if we don't need to read the sheet for anything else?

• ✭✭

E# is not F. On a piano keyboard it could be, but that only applies when the score is C major.

• ✭✭✭✭✭

They've still got to be some kind of red herrings, as the notes include Eb(D#) A# E# Cb(B#) and Db(C#). No piano has that many black keys in any grouping, it's all in groupings of 2 and 3.

• ✭✭

I noticed the funny notation. Does this make these notes special in some other way?(cryptographically speaking)

First Staff

C C G C C A A# C Db

Second Staff

A B Cb E F# C# C Db B G

I don't know how to solve this challenge yet, but your transcription of the second row seems wrong because you ignore the bass clef used.

• ✭✭

Top has 22 spaces and bottom has 20. Am I counting that right?

What is the significance of the green line?

• ✭✭✭

Any hints from those that solved it?

I can read the notes, but I'm stuck trying to convert them to characters. No conversion gives "13ar" or a keyword.

• What kind of conversion is it supposed to be? Any hints?

• E-sharp is 1/32 of a beat, E-natural is 1/16 is lengthened by 1/2 and the C-flat is 1/8th. This is following the bars at the top of each of those notes.

• ✭✭✭✭✭

By 'beat' I mean one crotchet (quarter-note), as did the person I quoted.

• Still totally lost what do I need to be counting and no conversion so far gives me 13ar

• ✭✭

Got it on the first try. A very appropriate keyword.

• How did you get it on the first try how are you looking at it?

I believe this is the first challenge with mandatory application of cryptanalysis methodology. Are they getting harder? What do you think?

@quattro [redacted] Thank you.

Careful, if you don't C# you may Bb.

Edit: had to redact my original comment; in retrospect it gave too much away.

• ✭✭

done.

I'm sorry, I did not see it on the phone display.

• ✭✭✭✭✭

In order to apply cryptanalysis, you first have to know what to apply cryptanalysis on.

8 hours post challenge and not a single hint has been posted (unless the above counts). Yeah, I'd say this one is harder.

• ✭✭✭✭✭

There are entirely too few clues that don't immediately give too much away. I mean, even just pointing out "how many X are in a/an Y" is enough to take much of the challenge out of this one.

But there's a pleasant amount of obfuscation that accidentally made me look at an order of magnitude larger numbers of potential strings.

Agreed. In previous challenges I had at least a feeling that I was doing something right (and then with a hint or two I got it done). This one? Not a single thing. Like does every beat code a number somehow? Are the beats lengths important? Are legatos important? Maybe sum those beats or something? I still haven't got a single meaningful thingy.

• ✭✭✭✭

So I found a way to interpret the last four notes as ACAR —> 13AR ... maybe? Not sure why I should turn AC to 13 at that particular location though (other than to force the previous formats). Can some one who solved this tell me if this is on the right path, or am I just grasping at straws?

• I can read bass and treble clef, I've got all but one measure not adding up to two quarter beats. I can't make heads not tails of this.

• In my opinion it's fine. Because A is the first letter the alphabet and C is the third then ACAR = 13AR
