 ## Full specification
 
-1. Simple text file
-2. Each line represents a beep or a pause
-   1. Column one is a positive integer number of milliseconds
-   2. Column two is a positive integer frequency in Hz, or `0` which represents silence
-   3. Columns are separated by a space
-3. Line ending is unix format
-4. File extension is `.tune`
-5. Although not necessarily part of the tune, consider adding a silence at the end so that looped playback sounds good :-)
+1. Each line in the file is `<frequency> <duration>`
+   1. `<frequency>` is the frequency of the beep in Hz or `0` for silence
+   2. `<duration>` is the duration of the beep in milliseconds
+2. Line ending is unix format
+3. File extension is `.tune`
+4. Although not necessarily part of the tune, consider adding a silence at the end so that looped playback sounds good :-)
 
 Note: this is compatible with the [GRUB_INIT_TUNE](https://wiki.archlinux.org/title/GRUB/Tips_and_tricks#Play_a_tune) when using a `TEMPO` of 60,000 (bpm).
