I am glad you enjoyed it DarrenEngland! ๐ Regarding the intervals, I must say first that when I compose I rarely let many things guide me besides my ear. I leave most theoretical knowledge for the studying of others works or as a tool when some part sounds off. In spite of that, in this case, I think the intervals are common among baroque composers (at least, I believe Bach did use them in many of his pieces).
I think one of the reasons is that most of those rules are usually only applied in counterpoint and melodic exercises as a didactic method, but then they are often broken in non-didactic music (such as the augmented second, which is often found in pieces by Bach and others). However, in the case of one melodic line with such huge jumps, there is usually no need to justify the breaking of rules, since the melody can be considered to be composed of several lines. So, for example, the first jump from Do3 to Si3 would actually not be a jump, but rather a nothe in the bass (being Do3) and then a continuation of the main melody (the first Do4). The main melodic line would then be Do-Si-La-Re-Do-Si-La-Sol and both lower notes would be other voices.
However, as I said, I usually think like that only for justifying myself, since in the end most of it is done by ear (which, of course, will make my music wrong many times since my ears are not the best ๐
). However, I think it is still useful to think in composite lines any time the melody line makes some high jumps. Your version of the beginning is also equally nice, by the way! But it is based in other motives which probably would make me have to change all the rest of the piece. Thank you for the comments and using them for creating a new version of the beginning! It made me check all the notes again and I found a few mistakes, actually, so I changed some bass notes.
Thank you PaperComposer! I am glad you enjoyed it! ๐ I will surely make the Sarabande, even though I am being quite busy lately so for a few months my composition speed will surely decrease, so I am not sure when will it be out. I am also afraid that the slow lyricism of the sarabande dance will clash with the robotic and mechanical computer sound library... so I do not expect the Sarabande to sound beautiful or lyrical I guess ๐ฃ.
Regarding the comments, as I said to DarrenEngland, I kinda use my ears to guide me (and, also, I am usually not afraid to use the tritone, and sometimes I find it beautiful). In this case I like the effect of the tritone and, even though I know the C# is creating a tension towards D which does not resolve until much later, I find this tension satisfying. Thanks to that tension, somehow, I feel all the measures between that C#3 until the next D3 as an extension of the dominant, and it creates an effect that I like. I tried out the other suggestion and that one sounded nice. However, it was making me change too many things afterwards so I left it as it was. Thank you for the suggestions!
