# Acorduri

Sonic Pi ofera suport pentru denumirile standard ale acordurilor. Incearca singur:

    play chord(:E3, :minor)

Asa mai merge. Acum arata mai bine decat o lista bruta (si e mai usor de citit pentru altii). Ce alte acorduri mai suporta Sonic Pi? Ei bine, o multime. Incearca-le pe acestea:

- `chord(:E3, :m7)`
- `chord(:E3, :minor)`
- `chord(:E3, :dim7)`
- `chord(:E3, :dom7)`

## Arpegii

Putem transforma usor acordurile in arpegii cu functia ‘play_pattern’:

    play_pattern chord(:E3, :m7)

Ok, that’s not so fun - it played it really slowly. `play_pattern` will play each note in the list with a call to `sleep 1` after each call to `play`. We can use another function `play_pattern_timed` to specify our own timings and speed things up:

    play_pattern_timed chord(:E3, :m7), 0.25

Putem sa ii transmitem o lista de intervale de timp care va fi citita circular (dupa ultima valoare o reia de la inceput):

    play_pattern_timed chord(:E3, :m13), [0.25, 0.5]

Aceasta linie este echivalenta cu:

    play 52, sustain: 0.25
    sleep 0.25
    play 55, sustain: 0.5
    sleep 0.5
    play 59, sustain: 0.25
    sleep 0.25
    play 62, sustain: 0.5
    sleep 0.5
    play 66, sustain: 0.25
    sleep 0.25
    play 69, sustain: 0.5
    sleep 0.5
    play 73, sustain: 0.25
    sleep 0.25

Cum preferi sa scrii?

Note that `play_pattern` and `play_pattern_timed` alter the sustain of the notes to fill the times. You can remove this behavior by setting the `sustain:` opt to `0`:

    play_pattern_timed chord(:E3, :m13), [0.25, 0.5], sustain: 0
