We have created and posted a number of lovely one octave music notes on our online learning centre.
If you are learning to play some musical instruments and wanting to practise on simpler one octave only music, you can check it out at our new project here. Most of them can be played with one octave scale only instruments like the steel tongue drum, xylophone, kalimba, flute, whistle, glockenspiel, mini saxophone, mini piano, pan flute etc. Some songs include semi tones but still within one octave scale. Keep practising.
