So, I've been learning the soprano recorder and I'm absolutely loving my experience so far. However, I've been wanting to experiment with something a little bit deeper and lower, so I ordered me a Yamaha alto recorder which arrived just yesterday. I plan to explore the worlds of both soprano and alto to add even more fun to the mix. I just adore the sound of the alto, however I'm a bit confused about something..
The soprano is tuned in C, which makes the lowest note possible a low C. The alto is tuned in F, making the lowest note possible a low F. However, I find that all the songs that I play on my soprano can easily be played with the same fingering on the alto and sound almost identical! This may seem like a silly question, but why would this be? Is it simply since the fingering is the same, making the steps between the notes the same and in turn making the melody appear to be identical?
I'm not as familiar with music theory as I'd like to be, and this question is the basic of the basic. Could someone please clear this most fundamental confusion for me?
