+### Tone
+
+You can set the tone when having a conversation with Bard:
+
+```python
+async with BardClient() as bard:
+    _ = await bard.ask("When was Bard released?")
+
+    response = await bard.ask("When was Bard released?", tone="Professional")
+    print(response)
+```
+
+The available options for the `tone` parameter are:
+- `Professional`
+- `Casual`
+
+> [!NOTE]
+> It is recommended to use the `tone` parameter on subsequent prompts and not in the first one. This is because this feature is typically used to change the previous response, rather than define the entire conversation tone.
