Hi @Sans_On,

Good morning from Canada!

Try:

```ruby
use_synth :piano
3.times do
  play_chord [:d4, :d5]
  sleep 0.25
end

```

See what’s different? Programming can be hard. Computers are picky. You must pay attention. Don’t give up!

Hi,

In coding you have to take care of the syntax, a space can be enough to break the script.  
So i just indicate the good syntax for the begining then you will have to write yourself the whole code, it’s how you can learn by do it yourself  
So

```ruby
use_synth :piano
3.times do
  play_chord [:d4,:d5]
  sleep 0.25
  play_chord chord(:D5, :major)
  sleep 0.5
end

```

You have missed the `chord` instruction and you have added a wrong space before the root note `:D5`.  
Good luck

You’re welcome! You can learn a lot from the kind people here if you are courteous. You should also read the tutorial first. People can be busy.

I will run your program and show you how to fix the errors one by one.

First:

 ![image](https://europe1.discourse-cdn.com/flex017/uploads/sonic_pi/original/2X/d/dfeac65fde1da4e6bf1413a62188f28e65f7961f.png)

This means there is an extra end on line 36. Let’s take it out.

![image](https://europe1.discourse-cdn.com/flex017/uploads/sonic_pi/original/2X/6/6d9d4fa42550b0f71e08ea48697d80cc833c3094.png)

Next:

This means on line 5, you’re using `play_chord` wrong. You’re very close.

Let’s look at the documentation for the `play_chord` function. Go to Help \> Lang, and look for `play_chord`.

![image](https://europe1.discourse-cdn.com/flex017/uploads/sonic_pi/original/2X/d/d78c42be423c6f5919a36da1de98acbf7d8cd3d9.png)

If you look at example 3, you’ll find what you’re missing. (@nlb pointed this out too, so make sure to thank them!)

![image](https://europe1.discourse-cdn.com/flex017/uploads/sonic_pi/original/2X/0/037ed8b2ff9c78a461355379a44da5285764cd74.png)

Let’s try.

```ruby
use_synth :piano
3.times do
  play_chord [:d4, :d5]
  sleep 0.25
  play_chord chord(:D5, :major)
  sleep 0.5
  play_chord chord(:D5, :major)
  sleep 0.25
  
  play_chord chord(:A, :major)
  sleep 0.5
  play_chord chord(:A, :major)
  sleep 0.5
  
  play_chord chord(:G, :major)
  sleep 0.5
  play_chord chord(:G, :major)
  sleep 0.5
  
  play_chord chord(:A, :major)
  sleep 1
end

#Faster Piano
8.times do
  play_chord chord(:G, :major)
  sleep 0.25
end

8.times do
  play_chord chord(:A, :major)
  sleep 0.25
end

play_chord chord(:D5, :major)

```

This works because `chord(:D5, major)` gives you `[74, 78, 81]`.

There’s your I-V-IV-V, IV-V-I.

Again, computers are picky. You must pay attention. Let’s start from the top:

1. It’s `8.times` not `8.time`
2. Each “argument” for a function like `play` needs a comma. See what’s different here? `play :G2, release: 0.25, amp: 0.5`
3. `play[:D2, amp: 0.5]` is not how you use `play`. Let’s look at the documentation for `play` in Help \> Lang \> play. Example 3 looks like this: `play 62, pan: -1, release: 3`. You should follow that. `play :D2, amp: 0.5`
4. You have an extra `end` at the end of your code. Let’s remove it.

If you fix everything, you will get this. (Try to figure it out before you look at the answer.)

```ruby
#Faster Bass
8.times do
  play :G2, release: 0.25, amp: 0.5
  sleep 0.25
end

8.times do
  play :A2, release: 0.25, amp: 0.5
  sleep 0.25
end

play :D2, amp: 0.5

```

hello,

you have to remember that an `end` is always with a `do` as the do and the end creates a block. Inside this block you can write all the code you want to be as example repeated.  
For the latest line, you don’t need a block as the instruction is used only once. So no do neither end.  
Follow the tutorials, you will learn very fast. believe me.  
good luck

The only times when this is _not_ true is when you are using `if` and `for`. For example:

```ruby
for i in 0..2
  if i.even?
    puts i.to_s + " is even"
  end
end

```

I agree! If you really do want to learn to use Sonic Pi, you will have to do some work.

Good luck!

Yep. Absolutely ! I was too much focused on the times case
