I have cut & pasted from a reply to an Australian graduate's survey on Bassoon teaching regarding my first tutor of choice - "The Young Bassoonist" which I use with my own fingering chart (another matter altogether). I will send you a PDF to your email address.
A few details about The Young Bassoonist.
It is clearly laid out with fairly large staves / notes. No fingerings are offered.
Each tune is accompanied by a smaller preliminary c. 2.5 cm long stave with the new notes or intervals.
Tune 1 is Suo-Gan (1st version) using EDC 4/4
Tune 2 is Au Clair de la Lune (Extending downwards to BAG) 4/4
Tune 3 is Song of the Crib (same range) 3/4
All 3 use crotchets and minims and slurs. (repeats are also presented along with simple dynamics p pp mf mp although I encourage a full strong supported tone to start with).
Tune 4 is Song of the Volga Boatmen (open F, introduces a pair of quavers, cresc & decresc)
Tune 5 is O Come All Ye Faithful (new note middle G, range G-G, dotted crotchet / quaver)
Tune 6 is See Amid the Winter's Snow (movement C-G, B-G)
And so on introducing progressively: low F, 9/4, Bb, upper A, 2/2 3/2, B, C, dotted quaver / semiquaver, Bb, 6/8, low EDC, F#'s, Eb, Ab's, C#, upper D, C#, E Eb, F.
The tunes are a mix of hymns, folksongs mainly of British origin. Most are very approachable and seem to suit the bassoon's voice and character very well.
The arrangements are all by Sydney Lawton.
I find the progression rate varies from "steady", (the book may take a year or more to complete), to "race-horse", (it may be completed in a few months by a student with previous woodwind experience - including recorder).
