08:01 timotimo so ... what's the connection between playing a song in a key and playing a chord that has the same name as that key?
08:05 RabidGravy the notes in that chord are in the scale
08:06 RabidGravy so say, to keep it simple, you have a thing in the key of C, the notes in the scale are C, D, E, F, G, A, B
08:06 timotimo but the scale is bigger than the chord, right?
08:07 RabidGravy the basic C major chord is  C, E, G
08:07 timotimo right, because major third, perfect fifth, rightt?
08:08 RabidGravy yaw
08:58 MadcapJake joined #perl6-noise-gang
10:04 psch timotimo: the chord with first note of the scale as root is called the tonic.  it's the chord that all other natural triads directly or indirectly resolve to
10:04 timotimo "resolve"?
10:04 psch timotimo: to qualify, in major keys it's the resolution target
10:05 timotimo can you explain that in term of DNS?
10:05 psch yeah, try playing Fmaj, Gmaj, and Cmaj46 (i.e. E3, G3, C4) in a row
10:05 psch that's F A C, G H D, E G C
10:05 timotimo i don't have piano keys next to me right now ;(
10:06 timotimo they hardly overlap
10:09 psch http://vocaroo.com/i/s0eVx9cLwVdO
10:10 psch ...actually, that's not Cmaj46
10:10 psch wait, is it :/
10:10 timotimo my piano is unlikely to have 64bit
10:10 timotimo 46bit*
10:11 psch i'm bad with names of inversions :P
10:11 timotimo so, what should i be noticing about that recording?
10:11 timotimo what's an inversion?
10:11 psch playing the notes of a chord in a different ordering
10:11 psch i.e. the root on top
10:11 psch *e.g.
10:11 psch or the fifth at the bottom, with root and third on top
10:12 timotimo i don't think i have hands wide enough to play 5 below the root and 3 on top of it
10:12 psch C E G is a natural triad, C maj.  E G C is the first inversion
10:12 psch yeah i think you do :P
10:14 timotimo yeah?
10:14 psch anyway, the noticeable thing in the cadence above is that it leads to Cmaj
10:14 timotimo you told me to play Cmaj46 and the special thing is that it "leads to" Cmaj? what does "lead to" mean?
10:14 psch no, the *cadence*
10:14 psch Fmaj, Gmaj => Cmaj
10:15 timotimo oh, lead to as in "sounds good"?
10:15 psch yeah, with a bit more technical explanation if you want :)
10:15 timotimo i'm not sure i'd understand
10:16 psch http://vocaroo.com/i/s0o6sG5kJwoE
10:16 psch that's Fmaj, Gmaj, Emin
10:17 psch as a comparison
10:17 timotimo also sounds good :o
10:17 psch yeah, but it doesn't as easy rest on the last chord
10:17 psch *easily
10:17 psch note, nothing that sticks to chords in one key can really sound bad
10:18 psch i mean, it can sound formulaic or boring, but never *really* bad or wrong
10:18 psch well, if you stick with natural triads at least
10:19 timotimo "triad" just means three notes played at the same time?
10:19 timotimo what of the chords that you play with the additional 4th note? and the ones where you play the 4th note, but leave the 3rd out?
10:20 psch yeah, natural triads (in a given scale)  are those that you build from the notes in a scale in the "normal" pattern, that is root, third, fifth
10:20 psch you got an example for playing the 4th note but not the 3rd note?
10:20 timotimo no
10:20 timotimo just that i've been told about that
10:20 timotimo and don't remember what it was all about
10:21 timotimo i guess the 4th note would be a 7th interavl?
10:22 psch eh, not necessarily :)
10:23 psch jazz usually leaves out the root afaik vOv
10:23 psch but they're crazy so there :P
10:23 timotimo not necessarily?
10:23 timotimo are there more ways to put a 4th note into a chord than to make it a 7-interval?
10:23 psch yeah, C E G A for example :)
10:24 timotimo huh, a 6 directly after the 5?
10:24 timotimo why would that work, but not, say, C D E G?
10:25 psch that can work too
10:25 psch it's a bit close together, so i'd probably move the C up an octave
10:25 timotimo ugh
10:25 timotimo why don't i just lay my arm across the piano keys
10:33 psch http://vocaroo.com/i/s0SnGGTGWCoW
10:33 psch that's your C D E G at the start
10:33 psch as E C D G, though
10:35 timotimo hmm
10:46 psch https://youtu.be/M-fxCYiM0Oo like this :)
10:46 psch re: "arm across the piano keys"
10:47 timotimo wow, doge

20:14 timotimo did i ever mention how much i love the bomberman 64 OST? check out this song: https://www.youtube.com/watch?v=4qg0x07oaZY&list=PL5A99BE5D40532B3F&index=5
