How to make chord progressions 1-5-6-4 or C, G, Am, F as explained in the tutorial in sonic pi?

Hi
emlyn offered some examples here, which may help get you started:

Intro, and suggestions for simple tunes please

Here are a few of things I’ve created in the past, that may give you some ideas. There are links to the code if you go through to the Soundcloud pages.

PD-Pi

[brendanmac]

I thought I have a go myself. This is a fairly brute-force, lazy Saturday morning version. You’ll have to organise the progression and voicings yourself. But if, like me, you are lazy, the rpitch: opt for sample playback works surprisingly well on those samples; for example rpitch -5 will give you a G major chord, with an authentic (guitaristic) voicing.

PD-Pi

[edit]

In fact, using rpitch: you can create several chords, either major or minor, from only one chord. Here, for example is C major to A minor, with the caveat that the A minor voicing is not authentic, it simply shifts the C major voicing down 3 semitones.

with_fx :reverb, mix: 0.6, room: 0.8 do
  5.times do
    tick
    use_sample_defaults amp: 0.3
    sample gtr, [4, 9, 15, 5, 10].look
    # c3, e3 etc
    sleep 0.05
  end
  sleep 4
  5.times do
    tick
    use_sample_defaults amp: 0.3
    sample gtr, [4, 9, 15, 5, 10].look, rpitch: [-3, -4, -3, -3, -4].look
    # the 3rd of the chord is now minor
    sleep 0.05
  end
end

‘0-wavz’ folder you have shown. Are the .wav files in public domain. If it is in public domain can you share it.

[brendanmac]

No they are from the source you mentioned, the Philharmonia website, I simply edited and converted them to wavefiles in Audacity.

The philharmonia samples are free from Sound samples | Philharmonia

[HarryLeBlanc]

Thanks for the link! I’m always on the lookout for good free samples.
